\fIoption\fP is an input parameter describing the course of action\&. Possible values are defined in \fBpapi\&.h\fP and briefly described in the table below\&. The Fortran calls are implementations of specific options\&.

\fBPAPI_get_opt()\fP and \fBPAPI_set_opt()\fP query or change the options of the PAPI library or a specific event set created by \fBPAPI_create_eventset\fP \&. Some options may require that the eventset be bound to a component before they can execute successfully\&. This can be done either by adding an event or by explicitly calling \fBPAPI_assign_eventset_component\fP \&.

The C interface for these functions passes a pointer to the \fBPAPI_option_t\fP structure\&. Not all options require or return information in this structure, and not all options are implemented for both get and set\&. Some options require a component index to be provided\&. These options are handled explicitly by the \fBPAPI_get_cmp_opt()\fP call for 'get' and implicitly through the option structure for 'set'\&. The Fortran interface is a series of calls implementing various subsets of the C interface\&. Not all options in C are available in Fortran\&.

The reader is urged to see the example code in the PAPI distribution for usage of \fBPAPI_get_opt\fP\&. The file \fBpapi\&.h\fP contains definitions for the structures unioned in the \fBPAPI_option_t\fP structure\&.
