18.12.7 omp_get_interop_rc_desc
The interoperability routines provide mechanisms to inspect the properties associated with an omp_interop_t object. Such objects may be initialized, destroyed or otherwise used by an interop construct. Additionally, an omp_interop_t object can be initialized to omp_interop_none, which is defined to be zero. An omp_interop_t object may only be accessed or modified through OpenMP directives and API routines.
An omp_interop_t object can be copied without affecting, or copying, the underlying state. Destruction of an omp_interop_t object destroys the state to which all copies of the object refer.
| Enum Name | Contexts | Name | Property |
| omp_ipr_fr_id = -1 | all | fr_id | An intptr_t value that represents the foreign runtime id of context |
| omp_ipr_fr_name = -2 | all | fr_name | C string value that represents the foreign runtime name of context |
| omp_ipr_vendor = -3 | all | vendor | An intptr_t that represents the vendor of context |
| omp_ipr_vendor_name = -4 | all | vendor_name | C string value that represents the vendor of context |
| omp_ipr_device_num = -5 | all | device_num | The OpenMP device ID for the device in the range 0 to omp_get_num_devices() inclusive |
| omp_ipr_platform = -6 | target | platform | A foreign platform handle usually spanning multiple devices |
| omp_ipr_device = -7 | target | device | A foreign device handle |
| omp_ipr_device_context = -8 | target | device_context | A handle to an instance of a foreign device context |
| omp_ipr_targetsync = -9 | targetsync | targetsync | A handle to a synchronization object of a foreign execution context |
| omp_ipr_first = -9 |

OpenMP reserves all negative values for properties, as listed in Table 18.1; implementation-defined properties may use zero and positive values. The special property, omp_ipr_first, will always have the lowest property value, which may change in future versions of this specification. Valid values and types for the properties that Table 18.1 lists are specified in the OpenMP Additional Definitions document or are implementation defined unless otherwise specified.
| Enum Name | Description |
| omp_irc_no_value = 1 | Parameters valid, no meaningful value available |
| omp_irc_success = 0 | Successful, value is usable |
| omp_irc_empty = -1 | The object provided is equal to omp_interop_none |
| omp_irc_out_of_range = -2 | Property ID is out of range, see Table 18.1 |
| omp_irc_type_int = -3 | Property type is int; use omp_get_interop_int |
| omp_irc_type_ptr = -4 | Property type is pointer; use omp_get_interop_ptr |
| omp_irc_type_str = -5 | Property type is string; use omp_get_interop_str |
| omp_irc_other = -6 | Other error; use omp_get_interop_rc_desc |
Table 18.2 lists the return codes used by routines that take an int* ret_code argument.
