POSIX_MEMALIGN(3)	 BSD Library Functions Manual	     POSIX_MEMALIGN(3)

NAME
     posix_memalign — aligned memory allocation

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <stdlib.h>

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

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

     The requested 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).

RETURN VALUES
     The posix_memalign() function returns the value 0 if successful; other‐
     wise it returns an error value.

ERRORS
     The posix_memalign() function will fail if:

     [EINVAL]		The alignment parameter is not a power of 2 at least
			as large as sizeof(void *).

     [ENOMEM]		Memory allocation error.

SEE ALSO
     free(3), malloc(3), realloc(3), reallocf(3), valloc(3)

STANDARDS
     The posix_memalign() function conforms to IEEE Std 1003.1-2001
     (“POSIX.1”).

HISTORY
     The posix_memalign() function first appeared in FreeBSD 7.0.
