    SYNOPSIS

       #include <stdlib.h>
    int posix_memalign (void **ptr size_t alignment size_t size);
     

    DESCRIPTION

    The posix_memalign ();
    function allocates Fa size bytes of memory such that the allocation's base address is an even multiple of Fa alignment , and returns the allocation in the value pointed to by Fa ptr .

    The requested Fa alignment must be a power of 2 at least as large as sizeof (void * .);

    Memory that is allocated via posix_memalign ();
    can be used as an argument in subsequent calls to realloc(3), reallocf(3), and free(3).

    function returns the value 0 if successful; otherwise it returns an error value.  

    ERRORS

    The posix_memalign ();
    function will fail if:

    Bq Er EINVAL
    The Fa alignment parameter is not a power of 2 at least as large as sizeof (void * .);
    Bq Er ENOMEM
    Memory allocation error.
