+.Sh DESCRIPTION
+Function
+.Fn dwarf_srcfiles
+returns the source file names associated with a compilation unit.
+Source file names are returned as an array of NUL-terminated strings.
+.Pp
+Argument
+.Ar die
+should reference a DWARF debugging information entry descriptor with
+source file information, see
+.Xr dwarf 3 .
+Argument
+.Ar filenames
+should point to a location that will hold a pointer to the returned array
+of file names.
+Argument
+.Ar filenamecount
+should point to a location that will hold the number of file names returned.
+If argument
+.Ar err
+is not NULL, it will be used to store error information in case of an
+error.
+.Ss Memory Management
+The memory areas used for the file names and for array of pointers
+being returned are managed by the DWARF(3) library.
+The application should not attempt to directly free these memory areas.
+Portable code should indicate that the memory areas are to be freed
+by using
+.Xr dwarf_dealloc 3 .
+.Sh RETURN VALUES
+Function
+.Fn dwarf_srcfiles
+returns
+.Dv DW_DLV_OK
+when it succeeds.
+In case of an error, it returns
+.Dv DW_DLV_ERROR
+and sets the argument
