rt.dmain2

shared size_t _initCount;

Keep track of how often rt_init/rt_term were called.

int rt_init();

Initialize druntime. If a C program wishes to call D code, and there's no D main(), then it must call rt_init() and rt_term().

int rt_term();

Terminate use of druntime.

alias TraceHandler = TraceInfo function(void* ptr);

Trace handler

void rt_setTraceHandler(TraceHandler h);

Overrides the default trace hander with a user-supplied version.

Parameters:

TraceHandler h

The new trace handler. Set to null to use the default handler.

TraceHandler rt_getTraceHandler();

Return the current trace handler

Throwable.TraceInfo _d_traceContext(void* ptr = null);

This function will be called when an exception is constructed. The user-supplied trace handler will be called if one has been supplied, otherwise no trace will be generated.

Parameters:

void* ptr

A pointer to the location from which to generate the trace, or null if the trace should be generated from within the trace handler itself.

Returns:

An object describing the current calling context or null if no handler is supplied.

struct CArgs;

Provide out-of-band access to the original C argc/argv passed to this program via main(argc,argv).

int _d_run_main(int argc, char** argv, MainFunc mainFunc);

Sets up the D char[][] command-line args, initializes druntime, runs embedded unittests and then runs the given D main() function, optionally catching and printing any unhandled exceptions.
