VALLOC(3)             DragonFly Library Functions Manual             VALLOC(3)

NAME

valloc -- aligned memory allocation function

LIBRARY

Standard C Library (libc, -lc)

SYNOPSIS

#include <unistd.h> void * valloc(size_t size);

DESCRIPTION

The valloc() function is obsoleted by the current version of malloc(3), which aligns page-sized and larger allocations. 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 prop- erly aligned pointer.

RETURN VALUES

The valloc() function returns a pointer to the allocated space if suc- cessful; otherwise a null pointer is returned

HISTORY

The valloc() function appeared in 3.0BSD.

BUGS
