I want to write my own custom assert handlers and to do this I need to trigger a breakpoint from the code. Is there a way to trigger a coded stop/breakpoint in xcode?

The Debugging Magic technote <http://developer.apple.com/technotes/tn2004/tn2124.html#SECCORESERVICES > says this:

Core Services includes a number of routines (for example, Debugger, DebugStr, and SysBreak) that enter the debugger with a message. If you set the USERBREAK environment variable to 1, these routines will send a SIGINT signal to the current process, which causes you to break into GDB. Xcode has GUI to enabled this facility (the "Break on Debugger() and DebugStr()" checkbox in the Debugging panel of the executable inspector [...]).


Cheers,
Ken
