es_exec_arg(_:_:)

Gets the argument at the specified position from a process execution event.

Declaration

func es_exec_arg(_ event: UnsafePointer<es_event_exec_t>, _ index: UInt32) -> es_string_token_t

Parameters

  • event:

    The process execution event.

  • index:

    The zero-based index of the argument to return. Attempting to read an out-of-bounds index — where index >= es_exec_arg_count() — results in undefined behavior.

Return Value

A string token that contains the argument data and its length.

Discussion

This function doesn’t allocate memory for the returned token; it points to a string token inside of event. Because you don’t own this memory, don’t try to free it.
