Digital UNIX Diffs - vms-vaxc(5)	      Digital UNIX Diffs - vms-vaxc(5)

NAME
       vms-vaxc -  OpenVMS VAX C vs DEC C Differences

DIFFERENCES
       OpenVMS has 2 C compilers: VAX C and DEC C.  VAX C is an older compiler
       and runtime library than DEC C.	VAX C predated the recent  ANSI	 stan‐
       dards and as a result is more relaxed implementation of the C language.
       DEC C is available on both OpenVMS and Digital UNIX; VAX C is not.

       Each compiler has its own runtime library on OpenVMS: the VAX C Runtime
       Library	and  the  DEC  C  Runtime  Library.  The functions in the vms-
       vaxc(5) category have different runtime semantics between these 2  run‐
       time  libraries.	 Thus if you are porting from OpenVMS VAX C to Digital
       UNIX DEC C, you should review these semantic differences.  Most of  the
       differences  result from DEC C adhering to the recent ANSI standard for
       C.
