Computing an MD5Sum in C

Is it possible to call the unix command md5sum from within a C program. I am trying to write a C program that scans a directory and computes the MD5Sum of all the files in the directory. Whenever I use md5sum 'filename' I get the error 'md5sum undeclared'. Is there a header file or some library that I can include? Thanks for your help.
