NAME
mempcpy, wmempcpy - copy memory area
SYNOPSIS
#define _GNU_SOURCE /* See feature_test_macros(7) */ #include <string.h> void *mempcpy(void *dest, const void *src, size_t n); #define _GNU_SOURCE /* See feature_test_macros(7) */ #include <wchar.h> wchar_t *wmempcpy(wchar_t *dest, const wchar_t *src, size_t n);
DESCRIPTION
The mempcpy() function is nearly identical to the memcpy(3) function. It copies n bytes from the object beginning at src into the object pointed to by dest. But instead of returning the value of dest it returns a pointer to the byte following the last written byte. This function is useful in situations where a number of objects shall be copied to consecutive memory positions. The wmempcpy() function is identical but takes wchar_t type arguments and copies n wide characters.
RETURN VALUE
dest + n.
VERSIONS
mempcpy() first appeared in glibc in version 2.1.

EXAMPLE
void * combine(void *o1, size_t s1, void *o2, size_t s2) { void *result = malloc(s1 + s2); if (result != NULL) mempcpy(mempcpy(result, o1, s1), o2, s2); return result; }
