C fstat, st_uid and alphanumeric userID
 
Hello everyone.
I have a problem. I need to compare the uid of a file with uid provided to me by a user. Problem is that when I use fstat and st_uid I get an integer (well, uid_t format) uid associated with alphanumeric userid and user is providing me with his alphanumeric userid.
Question: is there any way in C to get corresponding integer uid knowing alphanumeric one ore vice versa so I can compare them?
Thanks in advance.
