The application developer might want to use RACF® to control access to a set of resources that are managed by an application server. Through z/OS UNIX, the auth_check_resource_np(BPX1ACK) callable service enables application servers to invoke RACF authorization services. This service is also supported by the C runtime library through the __check_resource_auth_np() function call.

The service allows z/OS UNIX application servers to perform authorization checking for resources that are defined to RACF general resource classes. For more information on the auth_check_resource_np callable service, see z/OS UNIX System Services Programming: Assembler Callable Services Reference.
