CPI-C advanced function calls:
This group contains a subset of the X/Open advanced function calls. SAP provides a subset of the
X/Open CPI-C advanced function calls for external programs.
You use CMSPLN (Set_Partner_LU_Name) and CMSTPN (Set_Transaction_Program_Name) to set
the partner LU and partner transaction programs. CMSPLN and CMSTPN only make sense after a
CMINIT and before a CMALLC, i.e. only in programs which set up a connection. Then, you can
overlay the contents of the side information file.
CMCNVO (Convert_Outgoing) and CMCNVI (Convert_Incoming) are the function calls for
converting data from EBCDIC to ASCII and vice-versa.
CMFLUS (Flush) immediately transfers network buffer data to the partner program.
