// this is a dprintf wrapper

|
|
// there are three kinds of messages:
|
|
// flow: used to trace execution
|
|
// info: tells things that are important but not an error
|
|
// error: used if something has gone wrong
|
|
//
|
|
// common usage is
|
|
// SHOW_{FLOW,INFO,ERROR}( seriousness, format string, parameters... );
|
|
// SHOW_{FLOW,INFO,ERROR}0( seriousness, string );
|
|
//
|
|
// with
|
|
// seriousness: the smaller the more serious (0..3)
|
|
// format string, parameters: normal printf stuff
|
|
//
|
|
// to specify the module that created the message you have
|
|
// to define a string called
|
|
// DEBUG_MSG_PREFIX
|
|
// you dynamically speficify the maximum seriousness level by defining
|

// the following variables/macros
|
|
// debug_level_flow
|

// debug_level_info

|
|
// DEBUG_WAIT_ON_MSG (for flow and info)
|

// DEBUG_WAIT_ON_ERROR (for error)
