_seed48() unsigned short * _seed48 ( unsigned short  xseed[] ) Initialization with 48-bit seed for drand48, lrand48 and mrand48 (Linear congruential method) Purpose This routine initializes drand48, lrand48 and mrand48. Returns Pointer to the previous seed (16-bit x 3). (the contents will be updated when this routine is called) Parameters [in] xseed[] Array xseed[3] 48-bit (16-bit x 3) seed. Function call with the following arguments is equivalent to calling srand48(seed).   xseed[0] = 0x330e;   xseed[1] = seed % pow(2, 16);   xseed[2] = seed / pow(2, 16); 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 seed. 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.
