Detailed Description

rocsparse_cscsort_buffer_size returns the size of the temporary storage buffer required by rocsparse_cscsort(). The temporary storage buffer must be allocated by the user.

Note

This function is non-blocking and executed asynchronously with respect to the host. It can return before the actual computation has finished.

This routine supports execution in a hipGraph context.

Parameters

[in]	handle	- handle to the rocSPARSE library context queue.
[in]	m	- number of rows of the sparse CSC matrix.
[in]	n	- number of columns of the sparse CSC matrix.
[in]	nnz	- number of non-zero entries of the sparse CSC matrix.
[in]	csc_col_ptr	- array of n+1 elements that point to the start of every column of the sparse CSC matrix.
[in]	csc_row_ind	- array of nnz elements containing the row indices of the sparse CSC matrix.
[out]	buffer_size	- number of bytes of the temporary storage buffer required by rocsparse_cscsort().

Return values

rocsparse_status_success	the operation completed successfully.
rocsparse_status_invalid_handle	the library context was not initialized.
rocsparse_status_invalid_size	m, n, or nnz is invalid.
rocsparse_status_invalid_pointer	csc_col_ptr, csc_row_ind, or buffer_size pointer is invalid.
