.Bf -symbolic 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.
The valloc function returns a pointer to the allocated space if successful; otherwise a null pointer is returned
The valloc function appeared in BSD 3.0 .
A vfree function has not been implemented.
