L_DicomGetPreamble

#include "Ltdic.h"

L_VOID EXT_FUNCTION L_DicomGetPreamble(hDS, pPreamble, nLength)

HDICOMDS hDS;	/* a DICOM handle */
L_CHAR * pPreamble;	/* character string */
L_UINT16 nLength;	/* length of pPreamble */

Gets the contents of the file’s preamble.

Parameter	Description
hDS	A DICOM handle.
pPreamble	Character string to be updated with the contents of the preamble.
nLength	Length of pPreamble, in bytes. The maximum length is DS_PREAMBLE_LENGTH, which is defined as 128.

Returns

None.

Comments

To set the Preamble use L_DicomSetPreamble.

If the value specified in nLength is >= DS_PREAMBLE_LENGTH, then pPreamble will be updated with the entire Preamble. If nLength is < DS_PREAMBLE_LENGTH, then pPreamble will be updated with a truncated version of the Preamble with length nLength.
