IDA Help: Create Function

 Action    name: MakeFunction
 

This command defines a new function in the disassembly text.

You can specify function boundaries using the anchor. If you don't specify any, IDA will try to find the boundaries automatically:

   - function start point is equal to the current cursor position;
   - function end point is calculated by IDA.

A function cannot contain references to undefined instructions. If a function has already been defined at the specified addresses, IDA will jump to its start address, showing you a warning message.

A function must start with an instruction.
