VALLOC(3)               NetBSD Library Functions Manual              VALLOC(3)


NAME

     valloc -- aligned memory allocation function


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

     #include <stdlib.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

     A vfree() function has not been implemented.
