NAME

valloc − aligned memory allocator

SYNTAX

char *valloc(size)
unsigned size;

DESCRIPTION

The valloc subroutine 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. 

RESTRICTIONS

The vfree isn’t implemented. 

DIAGNOSTICS

The valloc subroutine 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.
