Abstract:
|
||
|
|
Defines a generic class that can be used to log
|
||
|
|
info from ISAPIs. This class allows its user to
|
||
|
|
create application specific logfiles and
|
||
|
|
automatically uses an intermediate file to log info and
|
||
|
|
creates permanent log files at predefined intervals
|
||
|
|
or after predefined number of records have been
|
||
|
|
written to the intermediate file.
