Function Documentation

ghost_error ghost_bincrs_header_read	(	ghost_bincrs_header_t *	header,
		char *	path
	)

Here is the call graph for this function:

int ghost_sparsemat_rowfunc_bincrs	(	ghost_gidx	row,
		ghost_lidx *	rowlen,
		ghost_gidx *	col,
		void *	val,
		void *	arg
	)

Parameters

row
rowlen
col
val

Returns

If called with row #GHOST_SPARSEMAT_ROWFUNC_BINCRS_ROW_INIT, the parameter val has to be a ghost_sparsemat_rowfunc_bincrs_initargs * with the according information filled in. The parameter col has to be a ghost_gidx[2] in which the number of rows and columns will be stored.
