valloc —
aligned memory allocation function
#include
<unistd.h>
void *
valloc(
size_t
size);
The
valloc() function is
obsoleted by the current version of
malloc(3), which aligns
page-sized and larger allocations, and
posix_memalign(3), which
allocates memory with a given alignment.
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.
The
valloc() function returns a pointer to
the allocated space if successful; otherwise a null pointer is returned.
malloc(3)
The
valloc() function appeared in
3.0BSD.
A
vfree() function has not been
implemented.
