The POSIX library functions and variables listed below are available without POSIX functionality, i.e. without specifying the link option $.SYSLNK.CRTE.POSIX. They are described in the manual “C Library Functions for POSIX Applications”. For some of these functions, the header file specified in the description is not available in the $.SYSLIB.CRTE library, but only in the $.SYSLIB.POSIX-HEADER library.
