TraceHandler alias TraceHandler = Throwable.TraceInfo function(void* ptr): Trace handler

Functions

_d_run_main
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.
_d_traceContext Throwable.TraceInfo _d_traceContext(void* ptr): 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.
_d_wrun_main
int _d_wrun_main(int argc, wchar** wargv, MainFunc mainFunc): Windows-specific version for wide command-line arguments, e.g., from a wmain/wWinMain C entry point. This wide version uses the specified arguments, unlike narrow _d_run_main which uses the actual (wide) process arguments instead.
rt_getTraceHandler TraceHandler rt_getTraceHandler(): Return the current trace handler
rt_init 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().
rt_setTraceHandler void rt_setTraceHandler(TraceHandler h, Throwable.TraceDeallocator d): Overrides the default trace hander with a user-supplied version.
rt_term int rt_term(): Terminate use of druntime.

Structs

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

Variables

_initCount size_t _initCount;: Keep track of how often rt_init/rt_term were called.
