LDicomDS::GetPreamble

#include "Ltdic.h"

L_VOID LDicomDS::GetPreamble(pPreamble, nLength)

L_CHAR * pPreamble;	/* character string */
L_UINT16 nLength;	/* length of pPreamble */

Gets the contents of the file’s preamble.

Parameter	Description
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 LDicomDS::SetPreamble.

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.
