[SOLVED] How can I get file name and path from file descriptor?

Issue

I am developing a C application for linux in which I need the open file lists using process ids. I am traversing /proc/pid/fd directory for file descriptor. But how can I know file path and file name from file descriptor? Or any other method or api function should I use?

Thanks,

Solution

The manual describes /proc/pid/fd/ as:

This is a subdirectory containing one entry for each file which the process has open, named by its file descriptor, and which is a symbolic link to the actual file.

Therefore, you can call stat on each entry and retrieve metadata about the file.
