Generate a pseudo-random signed long integer
#include <stdlib.h> long mrand48( void );
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The mrand48() function uses a linear congruential algorithm and 48-bit integer arithmetic to generate a signed long integer uniformly distributed over the interval [-231, 231).
The jrand48() function is a thread-safe version of mrand48().
