1364 ### gdb_get_line_number TEXT [FILE]
1365 ###
1366 ### Search the source file FILE, and return the line number of a line
1367 ### containing TEXT.  Use this function instead of hard-coding line
1368 ### numbers into your test script.
1369 ###
1370 ### Specifically, this function uses GDB's "search" command to search
1371 ### FILE for the first line containing TEXT, and returns its line
1372 ### number.  Thus, FILE must be a source file, compiled into the
1373 ### executable you are running.  If omitted, FILE defaults to the
1374 ### value of the global variable `srcfile'; most test scripts set
1375 ### `srcfile' appropriately at the top anyway.
1376 ###
1377 ### Use this function to keep your test scripts independent of the
1378 ### exact line numbering of the source file.  Don't write:
1379 ###
1380 ###   send_gdb "break 20"
1381 ###
1382 ### This means that if anyone ever edits your test's source file,
1383 ### your test could break.  Instead, put a comment like this on the
1384 ### source file line you want to break at:
1385 ###
1386 ###   /* breakpoint spot: frotz.exp: test name */
1387 ###
1388 ### and then write, in your test script (which we assume is named
1389 ### frotz.exp):
1390 ###
1391 ###   send_gdb "break [gdb_get_line_number "frotz.exp: test name"]\n"
1392 ###
1393 ### (Yes, Tcl knows how to handle the nested quotes and brackets.
1394 ### Try this:
1395 ###     $ tclsh
1396 ###     % puts "foo [lindex "bar baz" 1]"
1397 ###     foo baz
1398 ###     %
1399 ### Tcl is quite clever, for a little stringy language.)
