#include \f[B]<infiniband/mlx5dv.h>\f[R]

\f[B]struct\f[R] mlx5dv_export_sizes {
    uint32_t var_attrs_size;
    uint32_t devx_umem_attrs_size;
    uint32_t devx_obj_attrs_size;

.SH DESCRIPTION
\f[I]mlx5dv_get_export_sizes()\f[R] returns the buffer sizes required by
the export/import APIs for each supported object type.
The caller should use these sizes to allocate data buffers before
calling the corresponding export/import functions.
.PP
The returned sizes reflect the library\[cq]s internal data layout and
may change between library versions.
