int setPriority(int p)

Sets the priority for the thread.

Arguments

• int p - Priority of the thread:
  • 0 - normal
  • 1 - above normal
  • -1 - below normal
  • 2 - high

  Notice

  If the value is higher than 3, 3 will be passed; if the value is lower than -3, -3 will be passed.

Return value

1 if the priority is set successfully; otherwise - 0.

int getPriority()

Returns the priority of the thread.

Return value

Priority of the thread:

• 0 - normal
• 1 - above normal
• -1 - below normal
• 2 - high

Arguments

• variable name - Function to be run: string - function name, int - function ID, object - class name.
  Notice

  You can also pass an ID of the external class method that can be obtained via functionid().
• variable v0 - If name is an object: class member name or ID; otherwise - function argument.
• variable v1 - An argument of a function/class member.

Return value

-1 if the function is not found; otherwise - function ID in the queue.
