NAME
valloc —
aligned memory allocation
function
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 and both
aligned_alloc(3) and
posix_memalign(3), which allocate memory with a given alignment.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.
SEE ALSO
HISTORY
The valloc() function appeared in
3.0BSD.
BUGS
A vfree() function has not been
implemented.
