  • signal handling (synchronous only)
  • coprocessing
  • memory allocation
  • diagnostic control
  • compatibility
  • inline machine code
  • program control
  • timing functions (except clock)
  • general utility
  • localization/multibyte character functions
  • math functions
  • string utility functions
  • character type macros
  • system interface functions (except getlogin, oslink, and system)
  • varying-length argument list functions
  • TCP/IP socket library (except configuration information functions)

The library functions in the following categories are not supported:

  • file management functions
  • UNIX style I/O functions (except isatty)
  • IUCV functions
  • CMS low-level I/O
  • MVS low-level I/O
