hi,
I want to see the source code of c library functions and system calls such as fopen,fclose, and read,write,readdir,closedir,etc functions. So i have downloaded the glibc-2.4. But i am not able to see complete implementation of those functions. many functions implementation is not there. Can any body guide me in this direction.

If you already downloaded the source of glibc go to the directory where you extracted it to. From here you can simply search the desired source file. In example of 'fopen' run:
The most obvious file of the output will be your source-file.

hi Flesym,
Thanks for the reply.
Actually i have downloaded that version. But i am unable to find some functions implementations. For example,( i want to see opendir function):
1. find . -name "opendir.c"
The output of the command is
./sysdeps/mach/hurd/opendir.c
./sysdeps/unix/opendir.c
./sysdeps/unix/sysv/linux/opendir.c
./dirent/opendir.c

2. Then i opened dirent/opendir.c
This file has this implementation
#include <errno.h>
#include <stddef.h>
#include <dirent.h>
/* Open a directory stream on NAME. */
DIR * __opendir (const char *name)
{
__set_errno (ENOSYS);
return NULL;
}
weak_alias (__opendir, opendir)
stub_warning (opendir)
#include <stub-tag.h>

Its not doing any thing.
Give me any Suggestion.

Rajesh

In this case chose the sysdeps-file "./sysdeps/unix/opendir.c" (it was also in your output).

EDIT:
Oh, and in your find-command, you should lead the filename with a '*' (like in my example), because some files have prefixes; for example the 'fopen' function is defined in 'iofopen.c'

hi Flesym,
Thanks for your help. I finally got the code for that.
