3.11.3 omp_get_interop_ptr – Obtain pointer-valued interoperability property ¶

Description:

The omp_get_interop_int function returns the pointer value associated with the property_id interoperability property of the passed interop object. The ret_code argument is optional, i.e. it can be omitted in C++ and Fortran or used with NULL as argument in C and C++. If successful, ret_code (if present) is set to omp_irc_success.

In GCC, the effect of running this routine in a target region that is not the initial device is unspecified.

GCC implements the OpenMP 6.0 version of this function for C and C++, which is not compatible with its type signature in previous versions of the OpenMP specification. In older versions, the type int* was used for the ret_code argument in place of a pointer to the enumerated type omp_interop_rc_t.

C/C++:

Prototype:

void *omp_get_interop_ptr(const omp_interop_t interop, omp_interop_property_t property_id, omp_interop_rc_t *ret_code)

Fortran:

Interface:	type(c_ptr) function omp_get_interop_int(interop, property_id, ret_code)
	use, intrinsic :: iso_c_binding, only : c_ptr
	integer(omp_interop_kind), intent(in) :: interop
	integer(omp_interop_property_kind) property_id
	integer(omp_interop_rc_kind), optional, intent(out) :: ret_code
