CSV Entry Points: HP-UX Systems
A C program calls Common Service Verbs through the following entry
point:
void ACSSVC_C (
void * vcbptr
);
The only parameter passed to the function is the address of a verb
control block (VCB). The VCB is a structure made up of variables that
identify the verb to be executed, supply information to be used by the
verb, and contain information returned by the verb when execution is
complete. Each verb has its own VCB structure, which is declared in the
header file acssvcc.h delivered with SNAplus2. Use #include to
include this file in any application program that issues Common Service
Verbs.
For compatibility with other CSV implementations, SNAplus2 also
provides the entrypoints ACSSVC_P and ACSSVC, which can be used in the
same way as ACSSVC_C. The entry points are defined in the CSV header
file acssvcc.h.
