Arguments:
| Name | Type | Description |
| hIGMedElemList | HIGMEDELEMLIST | HIGMEDELEMLIST handle to the Data Element List object. |
| lpString | LPCHAR | A far pointer to a memory location which will be filled with the data from the Current Data Element as a NULL-terminated character string. |
| size_of_lpString | DWORD | The variable which tells the function the length of lpString, in bytes, expressed as a DWORD. If you specify a string length that is not long enough to hold the data, the data will simply be truncated. |
Return Value:
Returns the number of ImageGear errors that occurred during the function call.
Supported Raster Image Formats:
This function does not process image pixels.
Remarks:
The marker to the Current Data Element can be moved using one of the MED_DCM_DS_move_...() functions.
Data Elements can be of many different data types (int, word, bytes, float, double, string, etc.), but this function will always convert the data to a string. To return the data in its "natural form", use MED_DCM_DS_curr_data_get().
