memccpy() — Copy bytes in memory
|Standards / Extensions||C or C++||Dependencies|
Single UNIX Specification, Version 3
#define _XOPEN_SOURCE #include <string.h> void *memccpy(void *__restrict__ s1, const void *__restrict__ s2, int c, size_t n);
The memccpy() function copies bytes from memory area s2 into memory area 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 successful, memccpy() returns a pointer to the byte after the copy of c in s1.
If c was not found in the first n bytes of s2, memccpy() returns a NULL pointer.
