Info

In general, no command user interfaces or new flags were added to these commands, with the exception of the XCOFF-specific commands and the lint command. For most of the commands that deal with XCOFF files, a new flag was added, -X that requires an argument of either 32, 64, or 32_64. This flag indicates whether to recognize only 32-bit objects, 64-bit objects, or both. If both -X32 and -X64 are specified, the command treats it as -X32_64 and recognizes both object types. If only one of the options is specified, the command ignores all object files that are not of the specified type. If such objects are specified on the command line, an error message is issued, but other acceptable objects are still processed. If the -X option is given with an unrecognized argument, an error message is printed with the, usage statement and the command exits. For the same XCOFF-specific commands, the environment variable OBJECT_MODE determines the XCOFF file type(s) to be recognized. The defined values of OBJECT_MODE=32, OBJECT_MODE=64, and OBJECT_MODE=32_64 all have the equivalent function of their -X flag counterparts. If both the environment variable and the -X flag are specified, the flag takes precedence over the environment variable. If no -X flag is given and OBJECT_MODE is unset, 32-bit mode is used. If OBJECT_MODE is set to an undefined value, an error message is printed, and the command fails unless the value is overridden on the command line. 66 AIX Version 4.3 Differences Guide
Chapter 4. Application Development and Pthreads This chapter details the changes in AIX 4.3 that may have an impact on the work of application developers. Applications may exhibit better performance by using new features and functions that are available in AIX 4.3. 4.1 C Language Standards AIX Version 4 Release 3 made several changes and additions to conform to the ISO C Language Standard Normative Addendum One. The changes concern the handling of multibyte and wide character text formats. The changes include new and altered programming interface specifications, many of which are contained in new #include files. For more information, see the National Language Support chapter of AIX Version 4.3 General Programming Concepts: Writing and Debugging Programs. The document is part of the online documentation, which is supplied with AIX. If you have not installed the documentation on a local machine, it can also be viewed on the internet using the URL: http://www.rs6000.ibm.com/doc_link/en_US/a_doc_lib/aixgen/ 4.2 IEEE POSIX and UNIX98 Conformance AIX 4.3 is now aligned with the following standards: • ISO/IEC 9945-1:1996 that incorporates ANSI/IEEE Std POSIX 1003.1-1990, 1003.1b-1993, 1003.1c-1995, and 1003.1i-1995 (1003.1b-1993 and 1003.1i-1995 are realtime extensions; 1003.1c-1995 is a threads extension). • ISO C Amendment 1: 1995 (multibyte support). • The Open Group UNIX98 specification that adds: • Extended threads functions over POSIX threads, based on industry input from Sun, Digital, HP and DCE. • Dynamic linking extensions to permit applications to share common code across many applications and ease maintenance of bug fixes and performance enhancements for applications. • N-bit cleanup (64-bit and beyond) to remove any architectural dependencies in the UNIX specification. This is of particular relevance with the IBM move to 64-bit UNIX. • Year 2000 alignment to minimize the impact of the millennium rollover. 4.2.1 Realtime Options AIX 4.3 does not support the realtime optional parts of the IEEE POSIX and UNIX98 specifications. In particular, the routines provided in Table 16 are not supported in AIX Version 4.3. Table 16.
