app_data a set of additional data to be passed to the authCB if/when it is called authCB a callback routine use to gather additional authentication information on behalf of the print service encryption whether or not encryption should be used for communication with the print service, where applicable. If PAPI_ENCRYPT_IF_REQUESTED is specified, encryption will be used if the print service requests it. If PAPI_ENCRYPT_NEVER is specified, encryption will not be used while communicating with the print service. If PAPI_ENCRYPT_REQUIRED or PAPI_ENCRYPT_ALWAYS is specified, encryption will be required while communicating with the print service handle a pointer to a handle to be used for all libpapi operations. This handle should be initialized to NULL prior to creation password a plain text password to be used during any required user authentication with the print service function set with papiSer- viceSetAuthCB(). This provides the callback function a means of interrogating the service context for user information and setting a password. s the service context passed into the the authentication callback service_name the name of a print service to contact. This can be NULL, a print service name like "lpsched", a resolvable printer name, or a printer-uri like ipp://server/printers/queue. svc a handle (service context) used by subsequent PAPI calls to keep/pass information across PAPI calls. It generally contains connection, state, and authentication information. user_name the name of the user to act on behalf of while contacting the print service. If a value of NULL is used, the user name associated with the current processes UID will be used. Specifying a user name might require further authentication with the print service. DESCRIPTION
The papiServiceCreate() function creates a service context for use in subsequent calls to libpapi functions. The context is returned in the handle argument. This context must be destroyed using papiServiceDestroy() even if the papiServiceCreate() call failed. The papiServiceSet*() functions modifies the requested value in the service context passed in. It is recommended that these functions be avoided in favor of supplying the information when the context is created. The papiServiceGetStatusMessage() function retrieves a detailed error message associated with the service context. This message will apply to the last failed operation. The remaining papiServiceGet*() functions return the requested information associated with the service context. A value of NULL indicates that the requested value was not initialized or is unavailable. RETURN VALUES
Upon successful completion, papiServiceCreate() and the papiServiceSet*() functions return PAPI_OK. Otherwise, they return an appropriate papi_status_t indicating the type of failure. Upon successful completion, the papiServiceGet*() functions return a pointer to the requested data. Otherwise, they return NULL. EXAMPLES
