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
     A vfree function has not been implemented.
