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
malloc(3)
HISTORY
The valloc() function appeared in 3.0BSD.
BUGS
A vfree() function has not been implemented.
