gc_util_find_parm( ) — find a parameter in a GC_PARM_BLK gc_util_find_parm( ) find a parameter in a GC_PARM_BLK Name: GC_PARM_DATAP gc_util_find_parm(parm_blk, setID, parmID ) Inputs: GC_PARM_BLK *parm_blk pointer to GC_PARM_BLK where parameter is possibly located unsigned short setID set ID of parameter to be found unsigned short parmID parm ID of parameter to be found Returns: a pointer to GC_PARM_DATAP if successful NULL if the parameter is not found in the given GC_PARM_BLK Includes: gclib.h gcerr.h Category: GC_PARM_BLK utility Dialogic ® Platform and Technology: Mode: synchronous All Description The gc_util_find_parm( ) function is used to find a parameter in a GC_PARM_BLK. The gc_util_find_parm( ) function can be used to verify that a particular parameter exists, or to retrieve a particular parameter, or both. The function returns a pointer to the parameter if the parameter exists, or NULL if the parameter is not found in the specified GC_PARM_BLK. Parameter Description parm_blk points to a valid GC_PARM_BLK where the parameter is possibly located setID set ID of the parameter to be found parmID parm ID of the parameter to be found Termination Events None Cautions If the same parameter is included twice inside the GC_PARM_BLK, only the first instance of the parameter is returned. The pointer returned by gc_util_find_parm( ) can be used to modify that specific parameter within the GC_PARM_BLK. When the GC_PARM_BLK is modified, the changes will not take effect until the appropriate function, such as gc_SetConfigData( ), is called. The size of the data must remain the same. 374 Dialogic ® Global Call API Library Reference — January 2008 Dialogic Corporation
