1494 ### Search the source file FILE, and return the line number of a line
1495 ### containing TEXT. Use this function instead of hard-coding line
1496 ### numbers into your test script.
1498 ### Specifically, this function uses GDB's "search" command to search
1499 ### FILE for the first line containing TEXT, and returns its line
1500 ### number. Thus, FILE must be a source file, compiled into the
1501 ### executable you are running. If omitted, FILE defaults to the
1502 ### value of the global variable `srcfile'; most test scripts set
1503 ### `srcfile' appropriately at the top anyway.
1505 ### Use this function to keep your test scripts independent of the
1506 ### exact line numbering of the source file. Don't write:
1508 ### send_gdb "break 20"
1510 ### This means that if anyone ever edits your test's source file,
1511 ### your test could break. Instead, put a comment like this on the
1512 ### source file line you want to break at:
1514 ### /* breakpoint spot: frotz.exp: test name */
1516 ### and then write, in your test script (which we assume is named
1519 ### send_gdb "break [gdb_get_line_number "frotz.exp: test name"]\n"
1521 ### (Yes, Tcl knows how to handle the nested quotes and brackets.
1524 ### % puts "foo [lindex "bar baz" 1]"
1527 ### Tcl is quite clever, for a little stringy language.)
