NAME
valloc —
aligned memory allocation
function
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdlib.h>
void *
valloc(
size_t
size);
DESCRIPTION
The
valloc() function is obsoleted by the current version of
malloc(3), which aligns
page-sized and larger allocations.
The
valloc() function allocates
size
bytes aligned on a page boundary. It is implemented by calling
malloc(3) with a slightly larger
request, saving the true beginning of the block allocated, and returning a
properly aligned pointer.
RETURN VALUES
The
valloc() function returns a pointer to the allocated space
if successful; otherwise a null pointer is returned
HISTORY
The
valloc() function appeared in
3.0BSD.
BUGS
A
vfree() function has not been implemented.
