VALLOC(3) Library Functions Manual VALLOC(3)
valloc -- aligned memory allocation function
Standard C Library (libc, -lc)
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 3.0BSD.
A vfree() function has not been implemented.
