Function Documentation

MtkGridAttrGet()

MTKt_status MtkGridAttrGet	(	const char *	filename,
		const char *	gridname,
		const char *	attrname,
		MTKt_DataBuffer *	attrbuf
	)

Get a grid attribute.

Returns

MTK_SUCCESS if successful.

Example:

In this example, we get the Block_size.resolution_x attribute from the BlueBand grid in the file MISR_AM1_GRP_TERRAIN_GM_P161_O012115_DF_F03_0021.hdf

status = MtkGridAttrGet("MISR_AM1_GRP_TERRAIN_GM_P161_O012115_DF_F03_0021.hdf", "BlueBand",
              "Block_size.resolution_x", &attrbuf);

Note

The caller is responsible for using MtkDataBufferFree() to free the memory used by attrbuf

Parameters

[in]	filename	File name
[in]	gridname	Grid name
[in]	attrname	Attribute name
[out]	attrbuf	Attribute value

MTKt_status MtkGridAttrGetFid	(	int32	fid,
		const char *	gridname,
		const char *	attrname,
		MTKt_DataBuffer *	attrbuf
	)

Version of MtkFileGridAttrGet that takes an HDF-EOS file ID rather than a filename.

Returns
