| Function | WinMain |
| Include file | APP_MON.H |
| Prototype | int PASCAL WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpszCmdLine, int nCmdShow ) |
| Remarks | This is the main entry point for app_mon. |
![]()
| Function | process_cmd_line_4_arguments |
| Include file | APP_MON.H |
| Prototype | void process_cmd_line_4_arguments( LPSTR lpCmdLine ) |
| Remarks | Process the user's command line arguments into a argv array which then is processed by the normal getargs() procedure to store the data into the programs switch flags. |
![]()
| Function | WndProc |
| Include file | APP_MON.H |
| Prototype | long CALLBACK WndProc( HWND hWnd , UINT mesg , UINT wParam , LONG lParam ) |
| Remarks | This is a simple win proc for supporting the app_mon program. The only important thing done here is hanging a timer tick routine to support the checking the status of the monitored UDP ports. This is not the displaying window - the display is a dialog box. |
![]()
| Function | cnvt_2_seconds_past_midnight |
| Include file | APP_MON.H |
| Prototype | int cnvt_2_seconds_past_midnight( char *time_str ) |
| Remarks | Convert a HH:MM:SS time string into a integer value of total seconds since midnight. |
![]()
| Function | timer_tick |
| Include file | APP_MON.H |
| Prototype | void timer_tick( void ) |
| Remarks | This the main worker routine for app_mon. This routine controls the start-up of the port monitoring, the actual checking of all the monitored ports and the display update with the current program states. |
![]()
| Function | main_dialog_func |
| Include file | APP_MON.H |
| Prototype | long CALLBACK main_dialog_func( HWND hWnd , UINT mesg , UINT wParam , LONG lParam ) |
| Remarks | The is the main user interface object - a modal dialog box. The only functions that are supported are - resetting the display counts and status and exit the app. |
![]()
| Function | load_dialog_data |
| Include file | APP_MON.H |
| Prototype | void load_dialog_data( HWND hWnd ) |
| Remarks | Load the user interface dialog box with the current monitored appilcation names, counts and status. |
![]()
| Function | init_app_recs_channels |
| Include file | APP_MON.H |
| Prototype | void init_app_recs_channels( void ) |
| Remarks | This routine handles allocating and opening all the monitored udp ports. |
![]()
| Function | reset_app_recs |
| Include file | APP_MON.H |
| Prototype | void reset_app_recs( void ) |
| Remarks | Turn off all alarms and clear all counters for all the monitored applications. |
![]()
| Function | chk_the_ports |
| Include file | APP_MON.H |
| Prototype | void chk_the_ports( void ) |
| Remarks | This routine does the actual work of monitoring each application. It checks each port for current udp traffic or checks how long it has been since it heard something. If it has been too long it sets the crashed alarm and plays the crashed alarm wav file. If traffic is seen it just updates the counts and continues on. |
![]()
| Function | chk_rpt_tun_port |
| Include file | APP_MON.H |
| Prototype | void chk_rpt_tun_port( void ) |
| Remarks | This is a special port that I monitor from my unix system 24 hours per day unlike the other ports that I monitor just during the trading session (since they are carrying market data). This port is actually monitoring the state of my ppp connection. |
![]()
| Function | PlayResource |
| Include file | APP_MON.H |
| Prototype | BOOL PlayResource( HINSTANCE hInstance , char *pszSound ) |
| Remarks | This routine will load a wav file resource from an application's image file into memory and play it. |
