valloc - aligned memory allocation function



      valloc - aligned memory allocation function


      Standard C Library (libc, -lc)


      #include <unistd.h>
      void *
      valloc(size_t size);


      The valloc() function is obsoleted by posix_memalign(3), which can be
      used to request page-aligned allocations.
      The valloc() function allocates size bytes aligned on a page boundary.
      The valloc() function returns a pointer to the allocated space if suc‐
      cessful; otherwise a null pointer is returned.


      The valloc() function appeared in 3.0BSD.
      The valloc() function correctly allocated memory that could be deallo‐
      cated via free() starting in FreeBSD 7.0.


Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
