AEPutDesc(_:_:_:)

Adds a descriptor to any descriptor list, possibly replacing an existing descriptor in the list.

Declaration

func AEPutDesc(_ theAEDescList: UnsafeMutablePointer<AEDescList>!, _ index: Int, _ theAEDesc: UnsafePointer<AEDesc>!) -> OSErr

Parameters

  • theAEDescList:

    A pointer to the descriptor list to add a descriptor to. See Aedesclist.

  • index:

    A one-based positive integer indicating the position to insert the descriptor at. If there is already a descriptor in the specified position, it is replaced.

Return Value
