Interprocess communication using UNIX domain sockets

Manipulating byte strings (UNIX domain)

Aside from the address-related database routines, there are several other routines available in the run-time library which are intended mostly to simplify manipulation of names and addresses. The following table summarizes the routines for manipulating variable length byte strings.

C Run-Time Routines
Call Synopsis
memcmp(s1,s2,n) compare n bytes of strings s1 and s2
memcpy(s2,s1,n) copy n bytes from s1 to s2
memset(base,'\0',n) zero-fill n bytes starting at base
