NAME
bcopy -- copy byte string LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <strings.h> void bcopy(const void *src, void *dst, size_t len); DESCRIPTION
The bcopy() function copies len bytes from string src to string dst. The two strings may overlap. If len is zero, no bytes are copied. SEE ALSO
memccpy(3), memcpy(3), memmove(3), strcpy(3), strncpy(3) HISTORY
A bcopy() function appeared in 4.2BSD. Its prototype existed previously in <string.h> before it was moved to <strings.h> for IEEE Std 1003.1-2001 (``POSIX.1'') compliance. bcopy() was deprecated in IEEE Std 1003.1-2001 (``POSIX.1'') and removed in IEEE Std 1003.1-2008 (``POSIX.1''). BSD

NAME
bcmp, bcopy, bzero, memccpy, memchr, memcmp, memcpy, memmove, memset -- byte string operations LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <string.h> int bcmp(const void *b1, const void *b2, size_t len); void bcopy(const void *src, void *dst, size_t len); void bzero(void *b, size_t len); void * memchr(const void *b, int c, size_t len); int memcmp(const void *b1, const void *b2, size_t len); void * memccpy(void *dst, const void *src, int c, size_t len); void * memcpy(void *dst, const void *src, size_t len); void * memmove(void *dst, const void *src, size_t len); void * memset(void *b, int c, size_t len); DESCRIPTION
These functions operate on variable length strings of bytes. They do not check for terminating null bytes as the routines listed in string(3) do. See the specific manual pages for more information. SEE ALSO
bcmp(3), bcopy(3), bzero(3), memccpy(3), memchr(3), memcmp(3), memcpy(3), memmove(3), memset(3) STANDARDS
The functions memchr(), memcmp(), memcpy(), memmove(), and memset() conform to ISO/IEC 9899:1990 (``ISO C90''). HISTORY
The functions bzero() and memccpy() appeared in 4.3BSD; the functions bcmp(), bcopy(), appeared in 4.2BSD. BSD
