Getting source code for stdio.c

[thavali]

<<< split from dead thread stdio.c??? >>>
i downloaded source code of GCC from : svn://gcc.gnu.org/svn/gcc/trunk
And i try find the stdio.c file but i can't find it. Where is stdio.c stored ? In embedded system, we need re-direct the printf functions, so i need know how compiler can compile printf function if there hasn't stdio.c file ?

Thanks

The standard C libraries aren't part of the gcc package. gcc is just the compiler. What you want to find is the source code for glibc (GNU Lib C).

I mistook. which i need is source code of standard C libraries, which store stdio.c file. And i got stdio.c file in dir : glibc-2.10.1\libio but code in stdio.c has no implement printf function. please let me know where was the printf function implemented ? and where was the FILE struct which to control a I/O stream defined ?
