HP gnu source-level debugger 5992-4701 manual Getting help, Help , h

bubble(double,double) bubble(int,int)

((gdb)) b 'bubble(

In some cases, GDB can tell that completing a name requires using quotes. When this happens, GDB inserts the quote for you (while completing as much as it can) if you do not type the quote in the first place:

((gdb)) b bub TAB

GDB alters your input line to the following, and rings a bell:

((gdb)) b 'bubble(

In general, GDB can tell that a quote is needed (and inserts it) if you have not yet started typing the argument list when you ask for completion on an overloaded symbol.

For more information about overloaded functions, see “C++ expressions” (page 109). You can use the command set overload-resolution off to disable overload resolution; see “GDB features for C++” (page 111).
