pszName Character string that contains the name of the new Context Group.
bExtensible Value that specifies whether the new Context Group is Extensible. Possible values are:
  Value Meaning
  TRUE The new Context Group is Extensible.
  FALSE The new Context Group is Non-extensible.
pContextGroupVersion Pointer to a VALUEDATETIME structure that specifies the Context Group Version (0008,0106) of the new Context Group.
uFlags Flags that control the behavior of this function. This can be set to 0 or:
  Value Meaning
  DICOM_CONTEXTGROUP_DISALLOW_DUPLICATES [0x01] The function should fail if a Context Group with the same specified Context Identifier already exists in the Context Group Table.

Returns

!NULL

Pointer to a DICOMCONTEXTGROUP structure that specifies the newly inserted Context Group.

NULL

The function failed to allocate memory.

Comments

Please note that if the Context Identifier, Name, and Context Group Version of the new Context Group are not specified, the function fails and returns NULL.

A Context Group can be added to the Context Group Table either by loading it from the internal table maintained by LEADTOOLS or by inserting it directly into the Context Group Table. Use the L_DicomInsertContextGroup function to insert a new Context Group to the Context Group Table. Use the L_DicomLoadContextGroup function to load Context Groups from the internal table.

To add Coded Concepts to a Context Group in the Context Group Table, use the L_DicomInsertCodedConcept function.
