L_DicomFindContextGroup

Summary

Returns a pointer to the Context Group, in the Context Group Table, with the Context Identifier (CID) specified.

Syntax

#include "ltdic.h"

L_LTDIC_API pDICOMCONTEXTGROUP L_DicomFindContextGroup(pszContextID)

Parameters

L_TCHAR * pszContextID

Character string that contains a Context Identifier (CID). The function returns a pointer to the DICOMCONTEXTGROUP structure that specifies the Context Group in the Context Group Table which has this Context ID.

Returns

Value	Meaning
!NULL	Pointer to a DICOMCONTEXTGROUP structure that specifies the Context Group, in the Context Group Table, with the specified Context ID.
NULL	None of the Context Groups in the Context Group Table has the specified Context ID.

Comments

A Context Group is identified by its Context Identifier (CID). For a list of the Context Identifiers of the Context Groups maintained internally, refer to Context Identifier Values.

Notice that only the Context Groups in the Context Group Table are searched by the function: use the L_DicomLoadContextGroup and L_DicomInsertContextGroup functions to add Context Groups to the Context Group Table.

To search for a specific Coded Concept in a Context Group, use the L_DicomFindCodedConcept function.
