User exit routine UCCCLX is used with ISO-C support and is activated on return from an ISO-C library function if the exit point named CLX is active. User exit CLX is called from an ISO-C environment. Exit point CLX is located in the library startup code (CSTRTL).
Activation of this exit point is performed selectively on library load modules. The UXCMC macro specifies the library load modules to be activated. For example, the user exit point could be activated for the ISO-C library but not for a user-written library. The status of library user exits is propagated across all versions of a library.
