lrand48()

Generate a pseudo-random nonnegative long integer

Synopsis:

#include <stdlib.h>

long lrand48( void );

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The lrand48() function uses a linear congruential algorithm and 48-bit integer arithmetic to generate a nonnegative long integer uniformly distributed over the interval [0, 2³¹].

Call one of lcong48(), seed48(), or srand48() to initialize the random-number generator before calling drand48(), lrand48(), or mrand48(),

The nrand48() function is a thread-safe version of lrand48().

Returns:

A pseudo-random long integer.

Classification:

POSIX 1003.1 XSI
