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


#include <string.h>

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

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

void bzero(void *s, int n);

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.


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