5.6 acc_get_property – Get device property.


These routines return the value of the specified property for the device being queried according to devicenum and devicetype. Integer-valued and string-valued properties are returned by acc_get_property and acc_get_property_string respectively. The Fortran acc_get_property_string subroutine returns the string retrieved in its fourth argument while the remaining entry points are functions, which pass the return value as their result.

Note for Fortran, only: the OpenACC technical committee corrected and, hence, modified the interface introduced in OpenACC 2.6. The kind-value parameter acc_device_property has been renamed to acc_device_property_kind for consistency and the return type of the acc_get_property function is now a c_size_t integer instead of a acc_device_property integer. The parameter acc_device_property will continue to be provided, but might be removed in a future version of GCC.
