omp_init_allocator
– Create an allocator ¶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
OMP_ALLOCATOR
– Set the default allocator, 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.
