Disable Reading Source (Debugging with GDB)

### 9.7 Disable Reading Source Code ¶

In some cases it can be desirable to prevent GDB from accessing source code files. One case where this might be desirable is if the source code files are located over a slow network connection.

The following command can be used to control whether GDB should access source code files or not:

`set source open [on|off]` ¶
`show source open`

  When this option is `on`, which is the default, GDB will access source code files when needed, for example to print source lines when GDB stops, or in response to the `list` command.

  When this option is `off`, GDB will not access source code files.
