73 | /* The following routines deal with stdout/stderr data, which is created by |
74 | {f}printf_{un}filtered and friends. gdbtk_fputs and gdbtk_flush are the | |
75 | lowest level of these routines and capture all output from the rest of GDB. | |
76 | Normally they present their data to tcl via callbacks to the following tcl | |
77 | routines: gdbtk_tcl_fputs, gdbtk_tcl_fputs_error, and gdbtk_flush. These | |
78 | in turn call tk routines to update the display. | |

80 | Under some circumstances, you may want to collect the output so that it can |
81 | be returned as the value of a tcl procedure. This can be done by | |
82 | surrounding the output routines with calls to start_saving_output and | |
83 | finish_saving_output. The saved data can then be retrieved with | |
84 | get_saved_output (but this must be done before the call to | |
