posix_memalign(3c)

Standard C Library Functions                                posix_memalign(3C)



NAME
       posix_memalign - aligned memory allocation

SYNOPSIS
       #include <stdlib.h>

       int posix_memalign(void **memptr, size_t alignment, size_t size);

DESCRIPTION
       The  posix_memalign() function allocates size bytes aligned on a bound‐
       ary specified by alignment, and returns a pointer to the allocated mem‐
       ory  in  memptr. The value of alignment must be a power of two multiple
       of sizeof(void *).


       Upon successful completion, the value pointed to by memptr  will  be  a
       multiple of alignment.


       If  the  size of the space requested is 0, the value returned in memptr
       will be a null pointer.


       The free(3C) function will deallocate memory that has  previously  been
       allocated by posix_memalign().

RETURN VALUES
       Upon  successful  completion, posix_memalign() returns zero. Otherwise,
       an error number is returned to indicate the error.

ERRORS
       The posix_memalign() function will fail if:

       EINVAL    The value of the alignment parameter is not a  power  of  two
                 multiple of sizeof(void *).


       ENOMEM    There  is  insufficient  memory  available with the requested
                 alignment.
