-       fdmatch -- see if two file descriptors refer to same file
+Check to see if two open file descriptors refer to the same file.
+This is useful, for example, when we have an open file descriptor for
+an unnamed file, and the name of a file that we believe to correspond
+to that fd.  This can happen when we are exec'd with an already open
+file (@code{stdout} for example) or from the SVR4 @file{/proc} calls
+that return open file descriptors for mapped address spaces.  All we
+have to do is open the file by name and check the two file descriptors
+for a match, which is done by comparing major and minor device numbers
+and inode numbers.
