srand48() void srand48 ( long  seed ) Initialization with 32-bit seed for drand48, lrand48 and mrand48 (Linear congruential method) Purpose This routine initializes drand48, lrand48 and mrand48. Parameters [in] seed 32-bit integer seed (the remaining lower 16 bits of the internal buffer being set to 0x330e). Note If the random number generator is called without an initialization by seed48() or srand48(), it will be automatically initialized by using xseed[0] = 0x330e, xseed[1] = 0xabcd, and xseed[2] = 0x1234 as the parameters for seed48(). The multiplicand a and the addend c, set up by lcong48, will be reset to the default values. This routine is provided for Windows version.
