integer(kind(rocsparse_status_success)) function	rocsparse_csr_get_ (descr, rows, cols, nnz, csr_row_ptr, csr_col_ind, csr_val, row_ptr_type, col_ind_type, idx_base, data_type)

Get the fields of the sparse CSR matrix descriptor.

rocsparse_csr_get gets the fields of the sparse CSR matrix descriptor.

Parameters

[in]	descr	- the pointer to the sparse CSR matrix descriptor.
[out]	rows	- number of rows in the CSR matrix.
[out]	cols	- number of columns in the CSR matrix.
[out]	nnz	- number of non-zeros in the CSR matrix.
[out]	csr_row_ptr	- row offsets of the CSR matrix. Must be an array of length `rows+1`.
[out]	csr_col_ind	- column indices of the CSR matrix. Must be an array of length `nnz`.
[out]	csr_val	- values of the CSR matrix. Must be an array of length `nnz`.
[out]	row_ptr_type	- `rocsparse_indextype_i32` or `rocsparse_indextype_i64`.
[out]	col_ind_type	- `rocsparse_indextype_i32` or `rocsparse_indextype_i64`.
[out]	idx_base	- `rocsparse_index_base_zero` or `rocsparse_index_base_one`.
[out]	data_type	- `rocsparse_datatype_f32_r`, `rocsparse_datatype_f64_r`, `rocsparse_datatype_f32_c`, or `rocsparse_datatype_f64_c`.

Return values

rocsparse_status_success	the operation completed successfully.
rocsparse_status_invalid_pointer	if `descr`, `csr_row_ptr`, `csr_col_ind`, or `csr_val` is invalid.
rocsparse_status_invalid_size	if `rows`, `cols`, or `nnz` is invalid.
rocsparse_status_invalid_value	if `row_ptr_type`, `col_ind_type`, `idx_base`, or `data_type` is invalid.
