f course, you should be that there are other effects that the static keyword as applied here Q. My program comes up with the message Null pointer assignment after it terminates. What does this mean? A. Before a small-data model turbo C program returns to dos, it will check to see if the beginning of its data segment has been corrupted This message is to warn you that you have used uninitialized pointers or th t your program has corrupted memory in some other way. Q. Why are. EXE files generated by TC. eXe larger than those generated by TCC. EXE? A. In the default configuration, TC. eXe includes debugging nformation in the. exe files that it creates, and TCC. exe does not. If you don t want to produce this debugging information, you can shut it off in the Integrated Development Environment by selecting Alt-D/S/N. Q. Why do i get declaration syntax error messages on DOS. H? A. You have set the Ansi keywords only option oN. Keep this option OFF when using any keywords specific to Turbo C Q. I have a working program that dynamically allocates memory using malloch or calloc in small data models (tiny, smal and medium). When I compile this program in large data models (compact, large, and huge) my program hangs. A. Make sure that you have #include < alloc. h> in your program. Q. I am linking my own assembly language functions with Turbo C But the linker reports that all of my functions are undefined A. See answer above in the Linker section Q. My far pointers wrap around when they are incremented over 64K. How do i reference a data ob ject that is ter: : } } Of course, you should be aware that there are other effects that the "static" keyword has, as applied here. Q. My program comes up with the message 'Null pointer assignment' after it terminates. What does this mean? A. Before a small-data model Turbo C program returns to DOS, it will check to see if the beginning of its data segment has been corrupted. This message is to warn you that you have used uninitialized pointers or th t your program has corrupted memory in some other way. Q. Why are .EXE files generated by TC.EXE larger than those generated by TCC.EXE? A. In the default configuration, TC.EXE includes debugging information in the .EXE files that it creates, and TCC.EXE does not. If you don't want to produce this debugging information, you can shut it off in the Integrated Development Environment by selecting Alt-D/S/N. Q. Why do I get "declaration syntax error" messages on DOS.H? A. You have set the "Ansi keywords only" option ON. Keep this option OFF when using any keywords specific to Turbo C . Q. I have a working program that dynamically allocates memory using malloc() or calloc() in small data models (tiny, small, and medium). When I compile this program in large data models (compact, large, and huge) my program hangs. A. Make sure that you have #include <alloc.h> in your program. Q. I am linking my own assembly language functions with Turbo C. But the linker reports that all of my functions are undefined. A. See answer above in the "Linker" section. Q. My far pointers "wrap around" when they are incremented over 64K. How do I reference a data object that is greater than 64K? A. Use huge pointers
