NAME

intro − introduction to compatibility library functions

DESCRIPTION

These functions constitute a compatibility library.  They are part of /lib/clib, and are automatically loaded as needed by the C compiler cc(1).  Many of these routines have been rendered obsolete by newer ones.  They are included here so that older programs will compile and run, but their use in new programs should, for the most part, be avoided.  Manual entries for “obsolete” functions also name the newer, preferred, function.
