kcopy(9) [netbsd man page]

KCOPY(9)						   BSD Kernel Developer's Manual						  KCOPY(9)

NAME

     kcopy -- copy data with abort on page fault

SYNOPSIS

     #include <sys/systm.h>

     int
     kcopy(const void *src, void *dst, size_t len);

DESCRIPTION

     kcopy() copies len bytes from src to dst, aborting if a fatal page fault is encountered.

     kcopy() must save and restore the old fault handler since it is called by uiomove(9), which may be in the path of servicing a non-fatal page
     fault.  kcopy() returns 0 on success and an error number on failure.

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.

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.
