What are these tools and why are they important? 13 * There are two main tools here. The first tool is a tool for delaying or 14 * stopping gvim during startup. The second tool is a protocol log tool. 15 * 16 * The startup delay tool is called nbdebug_wait(). This is very important for 17 * debugging startup problems because gvim will be started automatically from 18 * netbeans and cannot be run directly from a debugger. The only way to debug 19 * a gvim started by netbeans is by attaching a debugger to it. Without this 20 * tool all starup code will have completed before you can get the pid and 21 * attach. 22 * 23 * The second tool is a log tool. 24 * 25 * This code must have NBDEBUG defined for it to be compiled into vim/gvim. 26 */ 27 28 #ifdef NBDEBUG 29 30 #include <stdarg.h> 31 32 #include "vim.h" 33 34 FILE *nb_debug = NULL; 35 u_int nb_dlevel = 0; /* nb_debug verbosity level */ 36 37 void nbdb(char *, ...); 38 void nbtrace(char *, ...); 39 40 static int lookup(char *); 41 #ifndef FEAT_GUI_W32 42 static int errorHandler(Display *, XErrorEvent *); 43 #endif 44 45 /* 46 * nbdebug_wait - This function can be used to delay or stop execution of vim. 47 * Its normally used to delay startup while attaching a 48 * debugger to a running process.
