valloc — aligned
memory allocation function
#include
<unistd.h>
void *
valloc(size_t
size);
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.
The valloc() function returns a pointer to
the allocated space if successful; otherwise a null pointer is returned.
The valloc() function appeared in
3.0BSD.
A vfree() function has not been
implemented.
