sys_backtrace [function]

sys_backtrace( bool as_string = false )

returns the call stack function/line/file list, either as array of dicts, or as a string, formatted exactly like in error messages (via sgs_PushErrorInfo)

• in the dict, there are three keys:
  • func (string)
  • line (null/int)
  • file (string)

errprint( sys_backtrace( true ) ); // print backtrace to stderr
println( sys_backtrace().last.func ); // print name of current function
