What information is provided for each
function?
For each WinHLLAPI function, the following information is presented:
• The function number together with its formal name,
• Brief description of the function purpose,
• Prerequisites
• Applicable session parameters
• Call parameters
• Return parameters
• Notes
Prerequisites
Many WinHLLAPI functions require another function to be called and successfully
completed before the desired call is issued. If the prerequisites are not satisfied, an
error code is returned. If None appears, no prerequisite calls are necessary.
Applicable session parameters
Function 9, “Set Session Parameters,” allows an application program to set optional
WinHLLAPI features, or session parameters. This section indicates whether any
session parameters affect this function and, if so lists the applicable parameters and
how they affect the function. If the function is not affected by any session
parameters, None appears.
