MEMCCPY(3P) POSIX Programmer's Manual MEMCCPY(3P)
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.
memccpy — copy bytes in memory
#include <string.h>
void *memccpy(void *restrict s1, const void *restrict s2,
int c, size_t n);
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.
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.
No errors are defined.
The following sections are informative.
None.
The memccpy() function does not check for the overflow of the
receiving memory area.
None.
None.
