Comments

NOTE: You must allocate the memory for pValue.

If you want to set more than one value in the Value Field of the Data Element, put all the string values in pValue and set nCount to the corresponding number of entries. For example, if you wish to set three string values in the Value Field of the Data Element, put all three strings in pValue, separated by the "0" delimiter and set nCount to three. For example, the illustration below shows a character string, containing three strings separated by the 0 delimiter.

For more information on required delimiters between multiple values, refer to An Overview of the DICOM File Format and the DICOM Standard.

If more than one value is stored in the Value Field of the Data Element, you must set all values at the same time.

This function can be called only if the Value Representation of the Data Element is VR_AE, VR_CS, VR_LO, VR_LT, VR_SH, VR_ST, VR_UI, VR_UT, or VR_PN. For more information about Value Representations, refer to Default Value Representation Table.
