NAME

intro − introduction to compatibility library functions

DESCRIPTION

These functions constitute the compatibility library portion of libc. They are automatically loaded as needed by the C compiler cc(1). The link editor searches this library under the “−lc” option. Use of these routines (instead of newer equivalent routines) is encouraged for the sake of program portability. Manual entries for the functions in this library describe the proper routine to use.
