VALLOC(3) — Unix Programmer’s Manual
NAME
valloc, vfree − aligned memory allocator
SYNOPSIS
char ∗valloc(size)
unsigned size; vfree(cp)
char ∗cp;
DESCRIPTION
Valloc allocates size bytes aligned on a boundary adequate for vread (2)). 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. Vfree must be used to dispose of the block.
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.
