SAP_CMINIT (SAP Library - SAP Communication: CPI-C Programming (BC-CST-GW))

SAP_CMINIT

Use

SAP_CMINIT passes the following additional parameters to the SAP-CPI-C interface:

Host, on which the SAP Gateway is running
Service, to which the SAP Gateway responds
Protocol type of the connection to be built

These values are needed to build the connection to the SAP Gateway.

The header file cpic.h indicates the prototypes.

In the following cases, SAP_CMINIT delivers a return code not equal to CM_OK:

The specified service is too long.
The specified host name is too long.
None of the values C, I, E or G was specified for the protocol.

Integration

You do not need to use the call SAP_CMINIT if you have defined all the parameters in the side information table.

For reasons of compatibility, you should always define the parameters in this table.

The above parameters are not needed for the CPI-C development library cpicslib, which is based on SNA.

The function SAP_CMINIT always returns the value CM_OK in this environment.

Activities

main (argv, argc)
..
SAP_CMINIT(argv, "compu01", "sapgw00", INT_SOCK_COMM);
..

The SAP Gateway runs on the host compu01 and responds to the service sapgw00. An internal communication is built. The partner program is therefore an ABAP program in an R/3 System.
