Machine Specific Notes:
=======================
1. HPUX-11.00 Patch Information:
   The following are the patches which were installed on the machine
   where the products were built and tested.
    Patch Name      Description
    ==========      ===========
    XSWCR1100                     B.11.00        Extension Software
                                                 Critical Patch Bundle
    XSWGR1100                     B.11.00.39     HP-UX Extension Pack,
                                                June 1998
    PHCO_14859                    1.0            cumulative 10.20 libc

    y2k1100                       0125  HP-UX Core OS Year 2000 Patch Bundle
2. This product is built and tested on HP B.11.00 U 9000/889 PA2.0 Architecture.
3. ESQL/C libraries are  supported as both static and shared libraries.
   The 'esql' script has been  changed to use either shared or static libraries.
   By default the script uses shared libraries.
   To use static libraries, the 'esql' script can be invoked as
        esql -static
   During execution of ESQL/C program, compiled with shared library you need
   to remember two points:
   A. Environment Variable LD_LIBRARY_PATH.
      Environment Variable LD_LIBRARY_PATH should be set to include
      $INFORMIXDIR/lib and $INFORMIXDIR/lib/esql. During runtime of the
      executable, dynamic loader will look for this path for Informix ESQL/C
      shared libraries.
      LD_LIBRARY_PATH=$INFORMIXDIR/lib:$INFORMIXDIR/lib/esql
        export LD_LIBRARY_PATH
        (for Bourne or Korn Shell)
      setenv LD_LIBRARY_PATH  $INFORMIXDIR/lib:$INFORMIXDIR/lib/esql
        (for C Shell)
4. The thread safe ESQL/C libraries are supported on this platform using
   POSIX threads.
   Please make sure to set the THREADLIB environment variable to posix.
         export THREADLIB=POSIX
        (for Bourne or Korn Shell)
         setenv THREADLIB POSIX
        (for C Shell)
   To build thread safe ESQL/C programs, use the following command:
      esql -thread prog.ec -o prog
   Applications that have not been compiled with the -thread option cannot be
   linked with applications that have been compiled with the -thread option.
   To do so, compile all applications with the -thread option.
5.    Migration of existing ESQL/C applications from 32 bit versions of
      INFORMIX-Client SDK to INFORMIX-Client SDK 2.40.FC1  .
        Informix recommends that ALL the existing applications should use
        the platform independent data types which are documented in
        "INFORMIX-ESQL/C Programmer's Manual, Version 2.40.FC1
        Chapter 5 "Working with Numeric Data Types".
        Existing 32-bit applications must be changed, if any of the below-
        mentioned ESQL/C library functions/data types/structures are being
        used. Special attention needs to be taken for the most commonly used
        elements such as the external variable SQLCODE, "sqlca" structure
        elements sqlca.sqlcode and sqlca.sqlerrd[] array.
5a. Internal Implementation of the following ESQL/C predefined data types
     is different from the 32 bit version.

       ESQL/C Predefined Data Type        C Language Data Type

       date                               Implemented as an int instead
                                          of long.

5b. ESQL/C Predefined data Types that have changed from the corresponding
    32 bit version of Informix Client-SDK 2.40.FC1
    are described as follows:-

     SQL Data    ESQL/C Predefined       Description of Change
     Type        Data type

     BYTE       loc_t                 The ESQL/C data type "loc_t" structure
                                      has changes to these members: lc_bufsize,
                                      lc_position, loc_indicator, loc_type,
                                      loc_size, loc_xfercount. These changes
                                      are in the Header File "locator.h".

     INT8      int8 or ifx_int8_t     The ESQL/C data type "ifx_int8_t"/"int8"
                                      structure has changes to the member "data".
                                      "data" is now an array of unsigned int
                                      instead of being an array of unsigned long.

5d. Other structures that have been modified for INFORMIX-ESQL/C
     Version 9.30.FC1  .

     In addition to the changes decsribed above, following types/structures
     are different for INFORMIX-ESQL/C Version 9.30.FC1
     compared with the corresponding 32 bit INFORMIX-ESQL/C 9.30
elvers.

     (i)   INFORMIX-ESQL/C header file "sqlca.h".
           For the sqlca structure declared in "sqlca.h" header file, member
           "sqlcode" is now an int4 instead of long. Member "sqlerrd" is now
           an array of int instead of being an array of long.
           Also, External variable SQLCODE  is now an int4 instead of being
           a long.

     (ii)  INFORMIX-ESQL/C header file "sqlda.h".
           The sqlda structure declared in the "sqlda.h" header file.
           This structure is used for holding data returned from a prepared
           statement. The sqlda structure has changed as follows: the members
           of the sub-member structure "sqlvar_struct" namely, sqllen, sqlxid,
           sqlsourceid, sqlflags are  int4 instead of being long.

3.   For shared library support, environment variable LD_LIBRARY_PATH needs to
     be set to include the $INFORMIXDIR/lib/c++ directories where C++ shared
     libraries are installed.
     For C shell, use
     setenv LD_LIBRARY_PATH $INFORMIXDIR/lib:$INFORMIXDIR/lib/c++:
    $INFORMIXDIR/lib/esql:$LD_LIBRARY_PATH
     For Bourne shell or Korn shell, use

3. The thread safe INFORMIX-ODBC libraries are supported for the current
   release.
4. UPDATE TO THE PRINTED DOCUMENTATION
    "INFORMIX-ODBC Programmer's Manual, Version 3.31.FC1  "

    This section contains updates to the printed CLI programmer's manual.
    The printed manual describes the ODBC programming interfaces/features
    visible to the customer for a 32 bit version of the Informix Client-SDK.
    Since this version of the Client-SDk is a 64 bit version, following
    Informix ODBC datatypes and API are defined in a different way to make it
    64-bit safe.
4a.  Informix ODBC Datatype             Mapped to C-Datatype
     --------------------               -------------------
     SQLINTEGER                          int instead of long.
     SQLUINTEGER                         unsigned int instead of
                                         unsigned long.

     SDWORD                              int instead of long.

     LONG                                int instead of long.

     UDWORD                              unsigned int instead of
                                         unsigned long int.

     LPARAM                              unsigned int instead of
                                         unsigned long int.

     BOOKMARK                            unsigned int instead of
                                         unsigned long int.

4b.  Informix ODBC API                  Description
     ---------------                    ----------
     SQLSetConnectOption               Accepts the parametes as

                                       (SQLHDBC ,SQLUSMALLINT, ULONG)
                                        instead of
                                       (SQLHDBC ,SQLUSMALLINT, SQLUINTEGER)
5.  Migration of existing ODBC applications from 32 bit versions of
    INFORMIX-Client SDK to INFORMIX-Client SDK 2.40.FC1  .

    ALL the existing 32-bit ODBC applications WILL need to be recompiled
    to make them work with INFORMIX-Client SDK 2.40.FC1  .
    Before recompiling these existing applications, changes will be
    required to make to the application sources, if above mentioned ODBC
    API and/or ODBC DAtatypes are being used. Also applications   should
    not have any "long" and/or "unsigned long" C-Data types declared
    which is being passed to any Informix ODBC APIs. Informix recommends
    use of SQLINTEGER/SQLUINTEGER, SDWORD/UDWORD standard ODBC types as
    defined in Informix header files.
