Information Provided for CPI-C Calls
The following information is supplied for each CPI-C call described in
this chapter:
• The pseudonym for the call, followed by the actual C function name
in parentheses (this information is in the section heading).
• The function prototype for the call, including the parameters used by
the call and the data type for each parameter. The prototype of each
function is declared in the file /usr/include/sna/cmc.h (HP-UX
systems) or wincpic.h (Windows systems).
For Windows The function prototypes for CPI-C calls shown in this chapter are in
the format used for HP-UX systems.
— For Win32 systems, replace “void functionname ” with “void
WINAPI functionname ” for each call.
End of Section • The Java method definition for the CPI-C function, if it is supported
in Java CPI-C.
• A description of each supplied and returned parameter. The
parameter names are pseudonyms. The actual variable names for
these parameters are declared by the application program. The
description includes the possible values of the parameter.
• The conversation state or states in which the call can be issued.
• The state or states into which the conversation can change upon
return from the call. Conditions that do not cause a state change,
such as parameter checks and state checks, are not noted.
• Additional information describing the use of the call.
