NAME
valloc —
aligned memory allocation
function
LIBRARY
library “libc”
SYNOPSIS
#include
<unistd.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.
