LDicomDS::SetPreamble

#include "Ltdic.h"

L_VOID LDicomDS::SetPreamble(pPreamble, nLength)

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

Sets the contents of the preamble.

Parameter	Description
pPreamble	Character string that contains the preamble to set.
nLength	Length of pPreamble. The maximum length is DS_PREAMBLE_LENGTH, which is defined as 128.

Returns

None.

Comments

The standard length of the Preamble is 128 bytes. You may use the constant DS_PREAMBLE_LENGTH, which is defined as 128, when setting nLength.

If the value specified in nLength is > DS_PREAMBLE_LENGTH, then the Preamble will be set with the first 128 bytes of pPreamble. If nLength is <= DS_PREAMBLE_LENGTH, then the Preamble will be set with the entire contents of pPreamble.

To retrieve the contents of the Preamble, call LDicomDS::GetPreamble.
