+.Sh DESCRIPTION
+This function is used for obtaining the file descriptor information
+of a particular process.

+.Pp
+This function is a wrapper around
+.Xr sysctl 3
+with the
+.Dv KERN_PROC_FILEDESC
+mib.
+While the kernel returns a packed structure, this function expands the
+data into a fixed record format.
+.Sh RETURN VALUES
+The
+.Fn kinfo_getfile
+function returns a pointer to an array of
+.Vt struct kinfo_file
+structures.
+The array was obtained by an internal call to
+.Xr malloc 3
+and must be freed by the caller with a call to
+.Xr free 3 .
