3.12.1 omp_init_allocator – Create an allocator ¶

Description:

Create an allocator that uses the specified memory space and has the specified traits; if an allocator that fulfills the requirements cannot be created, omp_null_allocator is returned.

The predefined memory spaces and available traits can be found at Memory allocation, where the trait names have to be prefixed by omp_atk_ (e.g. omp_atk_pinned) and the named trait values by omp_atv_ (e.g. omp_atv_true); additionally, omp_atv_default may be used as trait value to specify that the default value should be used.

C/C++:

Prototype:	omp_allocator_handle_t omp_init_allocator(
	omp_memspace_handle_t memspace,
	int ntraits,
	const omp_alloctrait_t traits[]);

Fortran:

Interface:	function omp_init_allocator(memspace, ntraits, traits)
	integer (omp_allocator_handle_kind) :: omp_init_allocator
	integer (omp_memspace_handle_kind), intent(in) :: memspace
	integer, intent(in) :: ntraits
	type (omp_alloctrait), intent(in) :: traits(*)
