User exit routine UCCCMCP is called whenever a create macro (CREDC, CREEC, CREMC, CRESC, CRETC, CREXC, or SWISC) is executed and the exit point named CMCP is active. Exit point CMCP is contained in CSECT CCNUCL.
UCCCMCP allows user information to be passed from a parent to a child entry control block (ECB). It is independent of macro servicing user exits. For calls from the $FORKC macro, passing information from a parent to a child ECB must be done in UCCCMCP because the UCCCMPI user exit will not be invoked.
General Conditions at Entry
The registers at entry to UCCCMCP are:
For calls from the $FORKC macro, R6 contains the address of the child ECB. For other calls, the content of R6 is undefined.
System Conditions at Entry
EVM, except for calls from the $FORKC macro in which case the address space is in SVM.
