Linux g++ question

[MoonWalker]

I have a prog in C++ compatible with the g++ compiler in Linux. There is a fuction in that, drand48().. What exaclty does it do and is there a similar function in VC++ 6 that I can use instead of drand48()??...

Thanks in advance,
MoonWalker

[int 21h]

#define drand48() (((double)rand())/((double)RAND_MAX))
