LDicomDS::GetConvertValue

#include "Ltdic.h"

L_UINT32 EXT_FUNCTION LDicomDS::GetConvertValue(pElement, pszText)

pDICOMELEMENT pElement;	/* pointer to a DICOMELEMENT structure */
L_CHAR *pszText;	/* character string */

Converts the value of an element to a string, and returns the number of characters in that string.

Parameter	Description
pElement	Pointer to a DICOMELEMENT structure within the Data Set.
pszText	Character string to be updated with the string version of the value.

Returns

Number of characters in the pszText parameter.

Comments

Call this function twice. The first should have pszText set to NULL. This will provide you with the size of the string that will be stored in pszText. Next, allocate the memory required for pszText and call this function again to update pszText with the string.
