MtkFileCoreMetaDataGet()

MTKt_status MtkFileCoreMetaDataGet	(	const char *	filename,
		const char *	param,
		MtkCoreMetaData *	metadata
	)

Get core metadata parameter.

Returns

MTK_SUCCESS if successful.

Example:

In this example, we get the value for LOCALGRANULEID from the core metadata in the file MISR_AM1_GRP_TERRAIN_GM_P161_O012115_DF_F03_0021.hdf

MtkCoreMetaData metadata = MTK_CORE_METADATA_INIT;
status = MtkFileCoreMetaDataGet("MISR_AM1_GRP_TERRAIN_GM_P161_O012115_DF_F03_0021.hdf", "LOCALGRANULEID", &metadata);

Note

The caller is responsible for using MtkCoreMetaDataFree() to free the memory used by metadata
