Debug and Trace Facilities
When the developer of a Windows Sockets 2 application encounters a Windows
Sockets-related bug there is a need to isolate the bug in 1) the application, 2)
the WS2_32.DLL, or 3) the service provider. Windows Sockets 2 addresses this
need through a specially devised version of the WS2_32.DLL and a separate
debug/trace DLL. This combination allows all procedure calls across the Windows Sockets
2 API or SPI to be monitored and, to some extent, be controlled.
Developers can use this mechanism to trace procedure calls, procedure returns,
parameter values, and return values. Parameter values and return values can be
altered on procedure call or procedure return. If desired, a procedure call
can be prevented or redirected. With access to this level of information and
control, a developer can isolate any problem in the application, WS2_32.DLL, or
service provider.
The Windows Sockets 2 SDK includes the debug WS2_32.DLL, a sample debug/trace
DLL, and a document containing a detailed description of the components. The
sample debug/trace DLL is provided in both source and object form. Developers are
free to use the source to develop versions of the debug/trace DLL that meet
their specific needs.
