INCOMPAT_USES_VECTORS

Previous Incompatibility Information Next

If your program is a TSR that hooks an interrupt or exception (see SetIntVec) or makes any other change to the interrupt vector table other than traps, you should write

#define INCOMPAT_USES_VECTORS
at the top of at least one source file, before including any header file from the TIGCC Library. If this directive is not used, a shell might automatically restore the hooked interrupt, rendering the TSR useless. Or it might even just free other resources allocated by the program, causing a crash.
