MEMCCPY(P) POSIX Programmer's Manual MEMCCPY(P)NAMEmemccpy - copy bytes in memory
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 unde‐
fined.
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.
