memccpy - Man Page

copy bytes in memory

Prolog

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.

Synopsis

#include <string.h>

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

Description

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.

Return Value

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.

Errors

No errors are defined.

The following sections are informative.

Examples

None.

Application Usage

The memccpy() function does not check for the overflow of the receiving memory area.

Rationale

None.

Future Directions

None.
