mempcpy, wmempcpy — copy memory area
#define _GNU_SOURCE #include <string.h>
void
*mempcpy( |
void * | dest, |
const void * | src, | |
size_t | n) ; |

size_t | n) ; |
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.
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; }
