Here’s an example converting an array of unsigned long data, most
significant element first, and host byte order within each value. unsigned long a[20];
/* Initialize z and a */
mpz_import (z, 20, 1, sizeof(a[0]), 0, 0, a); This example assumes the full sizeof bytes are used for data in the
given type, which is usually true, and certainly true for unsigned long everywhere we know of. However on Cray vector systems it may be noted that short and int are always stored in 8...
