Synopsis:
#include <malloc.h>
void *memalign( size_t alignment,
size_t size );
Arguments:
- alignment
- The alignment that you want to use for the memory.
This must be a multiple of size( void *).
- size
- The amount of memory you want to allocate, in bytes.
Library:
libc

Description:
The memalign() function allocates size bytes aligned on
a boundary specified by alignment.
Returns:
A pointer to the allocated block, or NULL if an error occurred
(errno
is set).
Errors:
- EINVAL
- The value of alignment isn't a multiple of size(void *),
or it's greater than the value of the MALLOC_MAX_ALIGNMENT environment variable or
the MALLOC_MAX_ALIGNMENT command to
mallopt().
