valloc — aligned
memory allocation function
#include
<unistd.h>
void *
valloc(size_t
size);
valloc() function is obsoleted by
the current version of malloc(3), which
aligns page-sized and larger allocations and both
aligned_alloc(3) and
posix_memalign(3), which allocate
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.
The valloc() function appeared in
3.0BSD.
A vfree() function has not been
implemented.
