L_DicomGetInfoDS

#include "Ltdic.h"

L_LTDIC_API L_VOID L_DicomGetInfoDS(hDS, pnClass, pnFlags)

HDICOMDS hDS;	/* a DICOM handle */
L_UINT32 * pnClass;	/* pointer to an IOD Class constant */
L_UINT16 * pnFlags;	/* flags that indicate file characteristics */

Gets information about the file.

Parameter	Description
hDS	A DICOM handle.
pnClass	Pointer to an IOD Class constant which determines the class of information stored in the file. For a list of default IOD Module Constants, refer to IOD Module Constants.
pnFlags	Meta-header flags and Transfer Syntax flags that indicate file characteristics. Possible values for the Meta-header flags are:
	Value	Meaning
	DS_METAHEADER_PRESENT	[0x0001] The header is present.
	DS_METAHEADER_ABSENT	[0x0002] The header is absent.
	Possible values and combinations for the Transfer Syntax flags are:
	DS_LITTLE_ENDIAN	[0x0004] Byte order is Little Endian.
	DS_BIG_ENDIAN	[0x0008] Byte order is Big Endian.
	DS_IMPLICIT_VR	[0x0010] The Value Representation is implicit.
	DS_EXPLICIT_VR	[0x0020] The Value Representation is explicit.
	DS_LITTLE_ENDIAN \| DS_IMPLICIT_VR
	DS_LITTLE_ENDIAN \| DS_EXPLICIT_VR
	DS_BIG_ENDIAN \| DS_EXPLICIT_VR

Any of the available Meta-header flags given above may be combined with any of the available values or combinations of values for the Transfer Syntax flags given above. For example, you may combine DS_METAHEADER_ABSENT with DS_EXPLICIT_VR, or you may combine DS_METAHEADER_PRESENT with DS_BIG_ENDIAN | DS_EXPLICIT_VR, etc.

Returns

None.
