Get Ancestor Handle Function

Get Ancestor Handle Function

Use the INFA_CTGetAncestorHandle() function when you want the procedure to access a parent handle of a given handle.
Use the following syntax:
INFA_CT_HANDLE INFA_CTGetAncestorHandle(INFA_CT_HANDLE handle, INFA_CTHandleType returnHandleType);
The following table describes the arguments for this function:
Argument
Datatype
Input/
Output
Description
handle
INFA_CT_HANDLE
Input
Handle name.
returnHandleType
INFA_CTHandleType
Input
Return handle type.
Use the following values for the returnHandleType parameter:
  • PROCEDURETYPE
  • TRANSFORMATIONTYPE
  • PARTITIONTYPE
  • INPUTGROUPTYPE
  • OUTPUTGROUPTYPE
  • INPUTPORTTYPE
  • OUTPUTPORTTYPE
The handle parameter specifies the handle whose parent you want the procedure to access. The Integration Service returns INFA_CT_HANDLE if you specify a valid handle in the function. Otherwise, it returns a null value.
To avoid compilation errors, you must code the procedure to set a handle name to the return value.
For example, you can enter the following code:
INFA_CT_MODULE_HANDLE module = INFA_CTGetAncestorHandle(procedureHandle, INFA_CT_HandleType);
