NAME
- -
- - memccpy, memchr, memcmp, memcpy, memmove, memset – memory operations
- -
-

SYNOPSIS
- -
- - #include <u.h> - #include <libc.h> - - - void* memccpy(void *s1, void *s2, int c, long n) - - - void* memchr(void *s, int c, long n) - - - int memcmp(void *s1, void *s2, long n) - - - void* memcpy(void *s1, void *s2, long n) - - - void* memmove(void *s1, void *s2, long n) - - - void* memset(void *s, int c, long n) - -
-

DESCRIPTION
- -
- - These functions operate efficiently on memory areas (arrays of - bytes bounded by a count, not terminated by a zero byte). They - do not check for the overflow of any receiving memory area. -
- - Memccpy copies bytes from memory area s2 into s1, stopping after - the first occurrence of byte c has been copied, or after n bytes - have been copied, whichever comes first. It returns a pointer - to the byte after the copy of c in s1, or zero if c was not found - in the first n bytes of s2. -
- - Memchr returns a pointer to the first occurrence of byte c in - the first n bytes of memory area s, or zero if c does not occur. - -
- - Memcmp compares its arguments, looking at the first n bytes only, - and returns an integer less than, equal to, or greater than 0, - according as s1 is lexicographically less than, equal to, or greater - than s2. The comparison is bytewise unsigned. -
- - Memcpy copies n bytes from memory area s2 to s1. It returns s1. - -
- - Memmove works like memcpy, except that it is guaranteed to work - if s1 and s2 overlap. -
- - Memset sets the first n bytes in memory area s to the value of - byte c. It returns s.

SOURCE
- -
- - All these routines have portable C implementations in /usr/local/plan9/src/lib9.

BUGS
- -
- - ANSI C does not require memcpy to handle overlapping source and - destination; on Plan 9, it does, so memmove and memcpy behave - identically. -
- - If memcpy and memmove are handed a negative count, they abort.
