RC = APPSRV_AUTHLIB( libname, memname, memtype, objname, objtype )
All arguments to this function are optional.
The APPSRV_AUTHLIB function determines if the Application Server program is authorized to access the specified data source. The function returns a value of 1 if authorized and 0 if not authorized. Authorization is determined by the contents of the AUTHLIB data set. This data set contains rules for including and excluding various data sources. For more details on the AUTHLIB data set, see Controlling Access to Data Sources with the AUTHLIB Data Set. An asterisk (*) can be supplied for any of the arguments to mean "any." If an argument is omitted, then an asterisk is assumed.
For the examples in Table 2, refer to the contents of the SASHELP.AUTHLIB data set in Table 1. Entities are excluded by default, and all exclude rules supersede all include rules.
