mlx5dv_get_export_sizes(3)                            Library Functions Manual

NAME
       mlx5dv_get_export_sizes - Query export buffer sizes for mlx5 objects

SYNOPSIS
              #include <infiniband/mlx5dv.h>

              struct mlx5dv_export_sizes {
                  uint32_t var_attrs_size;
                  uint32_t devx_umem_attrs_size;
                  uint32_t devx_obj_attrs_size;
              };

              void mlx5dv_get_export_sizes(struct mlx5dv_export_sizes *sizes);

DESCRIPTION
       mlx5dv_get_export_sizes() 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.

       The returned sizes reflect the library's internal data layout and may
       change between library versions.

ARGUMENTS
       sizes  Pointer to a struct mlx5dv_export_sizes to be filled.

   mlx5dv_export_sizes
       var_attrs_size
              Buffer size required for mlx5dv_var_export() /
              mlx5dv_var_import().

       devx_umem_attrs_size
              Buffer size required for mlx5dv_devx_umem_export() /
              mlx5dv_devx_umem_import().

       devx_obj_attrs_size
              Buffer size required for mlx5dv_devx_obj_export() /
              mlx5dv_devx_obj_import().
