I'm trying to identify when a particular process is running, based on its arguments, on Mac OS X. There may be several processes running with the same name, but only one will have the arguments I'm looking for. The processes are not owned by the same user who will be running my code. They will not have modified their argv in any way. ...

I compiled GDB 7 on a Mac OS X Leopard system. When stepping through a C program, GDB fails to step through 'printf()' statements, which probably don't have associated debug information, and starts printing "Cannot find bounds of current function."

I am wondering if there is a way to do this using Core Animation. Specifically, I am adding a sub-layer to a layer-backed custom NSView and setting its delegate to another custom NSView. That class's drawInRect method draws a single CGPath: - (void)drawInRect:(CGRect)rect inContext:(CGContextRef)context { CGContextSaveGState(context...
