NAME    [Toc]    [Back]

     valloc - aligned memory allocation function

SYNOPSIS    [Toc]    [Back]

     #include <unistd.h>

     void *
     valloc(size_t size);

DESCRIPTION    [Toc]    [Back]

     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 properly
 aligned pointer.

RETURN VALUES    [Toc]    [Back]

     The valloc() function returns a  pointer  to  the  allocated
space if successful;
 otherwise a null pointer is returned.

HISTORY    [Toc]    [Back]

     The valloc() function appeared in 3.0BSD.

BUGS    [Toc]    [Back]
