VALLOC(3) — Unix Programmer’s Manual
NAME
valloc − aligned memory allocator
SYNOPSIS
char ∗valloc(size)
unsigned 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 is not implemented.
