I have download the source code of gcc, using this command:

svn checkout svn://gcc.gnu.org/svn/gcc/trunk SomeLocalDir

Who can tell me where can I find the implementation of standard library function strncpy()?

Thank you.

gcc doesn’t actually contain the source of strncpy, as gcc contains the compiler code and not the standard library code.
