Sun Studio 12 Update 1: Debugging a Program With dbx

returns function

The returns function event executes each time the given function returns to its call site. This is not a temporary event. The return value is not provided, but you can find integral return values by accessing the following registers:

SPARC based systems

$o0

x86 based systems

$eax

x64 based systems

$rax, $rdx

The event is roughly equivalent to:


when in func { stop returns; }
