mrand not in mingw?

I use dev c++ for my c projects,because it's simple for me.I installed it with the mingw extension.Well,I included stdlib.h and made a call to mrand which according to manpages belongs to that header but I got a linker error.I looked in mingw's headers and found no declaration for mrand although the glibc ha开发者_StackOverflow中文版s one in stdlib.Am I missing something?I thought mingw and gcc were the same.If they are different I suppose that there isn't a way to get gcc's full power.Right?Thank you.

mrand is not part of the standard C library, nor is it present in standard Linux manpages. Whatever compiler you previously used may have had it as a proprietary extension, but since you haven't mentioned which (it's not GCC or MSVC, at least), I can't tell what mrand is supposed to do, and so it's hard to suggest an alternative function to use.

Note that glibc does offer a mrand48(). Since this is a POSIX function, not a standard C function, it may or may not be present in other C libraries - but note that this is a function of the C library (glibc), not the compiler (gcc/mingw).
