LPC Library Functions: trace

NAME

trace() - sets trace flags and returns the old ones

SYNOPSIS

int trace( int traceflags );

DESCRIPTION

Sets the trace flags and returns the previous trace flags. Tracing allows you to debug the flow of execution in mud objects, but can generate a lot of output. 'traceflags' is an integer composed of trace bits. The trace bits are:

   1 - Trace all function calls to lfuns.
   2 - Trace all calls to "call_other".
   4 - Trace all function returns.
   8 - Print arguments at function calls and return values.
  16 - Print all executed stack machine instructions (produces a lot of output!)
  32 - Enable trace in heart beat functions.
  64 - Trace calls to applies.
 128 - Show object name in tracing.

This efun is only available if the driver flags TRACE and PACKAGE_DEVELOP are defined.
