NAME

bcmp, bcopy, bzero, memccpy, memchr, memcmp, memcpy, memfrob, memmem, memmove, memset - byte string operations

SYNOPSIS

#include <string.h>

int bcmp(const void *s1, const void *s2, size_t n);

void bcopy(const void *src, void *dest, size_t n);

void bzero(void *s, size_t n);

void *memccpy(void *dest, const void *src, int c, size_t n);

void *memchr(const void *s, int c, size_t n);

int memcmp(const void *s1, const void *s2, size_t n);

void *memcpy(void *dest, const void *src, size_t n);

void *memfrob(void *s, size_t n);

void *memmem(const void *haystack, size_t haystacklen,
             const void *needle, size_t needlelen);

void *memmove(void *dest, const void *src, size_t n);

void *memset(void *s, int c, size_t n);

DESCRIPTION

The byte string functions perform operations on strings (byte arrays) that are not necessarily null-terminated. See the individual man pages for descriptions of each function.

NOTES

The functions bcmp(), bcopy(), and bzero() are obsolete. Use memcmp(), memcpy(), and memset() instead.
