L_DicomSetCharValue

#include "Ltdic.h"

L_LTDIC_API L_BOOL L_DicomSetCharValue(hDS, pElement, pValue, nCount)

HDICOMDS hDS;	a DICOM handle
pDICOMELEMENT pElement;	pointer to a DICOMELEMENT structure
L_UCHAR * pValue;	pointer to a character
L_UINT32 nCount;	number of values to set

Sets the character value(s) of a Data Element.

Parameter	Description
hDS	A DICOM handle.
pElement	Pointer to a DICOMELEMENT structure within the Data Set.
pValue	Pointer to a character or character string that contains the character value(s) to set. If you want to set multiple values in the Value Field, put all character values in this string and set nCount to the appropriate number of values.
nCount	Value that indicates the number of values to set in the Value Field. If you want to set multiple values in the Value Field, put all the character values in pValue and set nCount to the appropriate number.

Returns

TRUE	The character value(s) were set successfully.
FALSE	Could not set the character value(s) of the Data Element.

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 character values in pValue and set nCount to the corresponding number of entries. For example, if you wish to set three character values in the Value Field of the Data Element, put all three characters in pValue and set nCount to three.

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

A character has a standard size of one byte. When multiple characters are in pValue, the first byte of data is the first character, the second byte of data is the second character, etc. Therefore no delimiters are needed.

This function can be called only if the Value Representation of the Data Element is VR_OB, VR_SQ, or VR_UN. For more information about Value Representations, refer to Default Value Representation Table.
