VALLOC(3) Library Functions Manual VALLOC(3)
NAME
vallocaligned 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 properly aligned pointer.
RETURN VALUES
The valloc() function returns a pointer to the allocated space if successful; otherwise a null pointer is returned
HISTORY
The valloc() function appeared in 3.0BSD.
BUGS
A vfree() function has not been implemented.
