md5sum of file in Linux C

Question

I want to find md5sum of a file in Linux C, Is there any API where I can send file name to get md5sum of that file.

Answer 1

You can use the mhash library (license is LGPL). On Debian systems:

sudo apt-get install libmhash-dev

See the man page man 3 mhash

But I don't think you can just give it the name of a file. You have to open the file yourself, read the data, and feed the data to this library's functions.
