MEMCCPY(3P)             POSIX Programmer's Manual            MEMCCPY(3P)

ПРОЛОГ

       This manual page is part of the POSIX Programmer's Manual.  The
       Linux implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior),
       or the interface may not be implemented on Linux.

ИМЯ

       memccpy — copy bytes in memory

СИНТАКСИС

       #include <string.h>

       void *memccpy(void *restrict s1, const void *restrict s2,
           int c, size_t n);

ОПИСАНИЕ

       The memccpy() function shall copy bytes from memory area s2 into
       s1, stopping after the first occurrence of byte c (converted to
       an unsigned char) is copied, or after n bytes are copied,
       whichever comes first. If copying takes place between objects
       that overlap, the behavior is undefined.

ЗНАЧЕНИЕ ВОЗВРАТА

       The memccpy() function shall return a pointer to the byte after
       the copy of c in s1, or a null pointer if c was not found in the
       first n bytes of s2.
