L_UINT32 LDicomDS::GetConvertValue(pElement, Destination, DestSizeInWords)
pDICOMELEMENT pElement; |
/* pointer to a DICOMELEMENT structure */ |
L_TCHAR *Destination; |
/* character string */ |
L_UINT32 DestSizeInWords; |
/* size of the destination string buffer */ |
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. |
Destination |
Character string to be updated with the string version of the value. |
DestSizeInWords |
Size of the Destination buffer. |
Returns
Number of characters in the Destination parameter.
Comments
Call this function twice. The first should have Destination set to NULL. This will provide you with the size of the string that will be stored in Destination. Next, allocate the memory required for Destination and call this function again to update Destination with the string.
