MtkFileAttrGet()

MTKt_status MtkFileAttrGet	(	const char *	filename,
		const char *	attrname,
		MTKt_DataBuffer *	attrbuf
	)

Get a file attribute.

Example:

In this example, we get the Camera attribute from the file MISR_AM1_GRP_TERRAIN_GM_P161_O012115_DF_F03_0021.hdf

status = MtkFileAttrGet("MISR_AM1_GRP_TERRAIN_GM_P161_O012115_DF_F03_0021.hdf", "Camera", &attrbuf);

Note

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

Parameters

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