/* This routine is a convenient way to enable or disable various
|
|
debugging modules according to the wishes of the user. It takes a
|
|
result array from argv_process(3), parses the contents and set the
|
|
debug level of the specified modules accordingly.
|
|
|
|
The provided array must contain zero or more options describing how
|
|
the debug level should be set. Each string must be of the form
|
|
'module,level', 'module/level' or 'module:level', for example:
|
|
'rfcparse,5'. argvSetDebugLevel() will then set the debug level of
|
|
the module 'rfcparse' to '5'.
|
|
|
|
In order to be able to map the name of a debug module to the
|
|
according internal module number, argvSetDebugLevel() expects an
|
|
array string pointers of the name 'ModuleTable', which lists all
|
|
available module names in the order in which they have been
|
|
assigned an id number. This array will typically be provided by the
|
|
main() routine of the caller.
|
|
|
|
RETURNS: In case of an error, -1 is returned. A return code of 0
|
|
indicates success.
|

|
REQUIRES: extern const char * const ModuleTable[]
