NAME
valloc - aligned memory allocator

SYNOPSIS
void *valloc(size)
size_t size;

DESCRIPTION
Valloc 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.

DIAGNOSTICS
Valloc returns a null pointer (0) if there is no available memory
or if the arena has been detectably corrupted by storing outside
the bounds of a block.

BUGS
Vfree isn’t implemented.
