53 | DESCRIPTION: | |
54 | Handles fatal error and warning conditions for checked builds. | |
55 | ||
56 | HEADER: | |
57 | scitech.h | |
58 | ||
59 | REMARKS: | |
60 | This function is called whenever an inline check or warning fails in any | |
61 | of the SciTech runtime libraries. Warning conditions simply cause the | |
62 | condition to be logged to the log file and send to the system debugger | |
63 | under Window. Fatal error conditions do all of the above, and then | |
64 | terminate the program with a fatal error conditions. | |
65 | ||
66 | This handler may be overriden by the user code if necessary to replace it | |
67 | with a different handler (the MGL for instance overrides this and replaces | |
68 | it with a handler that does an MGL_exit() before terminating the application | |
69 | so that it will clean up correctly. | |
