Whenever a fatal error occurs, Quake II calls
Sys_Error
with a description of the error. The
client will be shut down and the arguments will be packed into a string and sent to the C to
Java callback of
jni_sys_error
.
va_start (argptr,error);
vsprintf (string,error,argptr);
va_end (argptr);
jni_sys_error(string);
jni_sys_error
then performs the following steps:
