information about this project |
during 1993 This
project was published in the computer magazine "ATARI ST Computer" somewhen in
1994; I don't exactly remember which issue. |
DESCRIPTION
|
The goal was to implement a C library which calculates a checksum of the program. The idea was
to detect manipulations caused by viruses. A binding to use the
C library from Pascal was also provided. Because I chose to use the image in memory, the
relocation done by the OS had to be "undone" for the calculations. (By reading
the relocation table; from disk actually... ;-) |
TECHNOLOGIES
|
| low-level C program |
| Atari OS (TOS) executable file format and relocation info |

LOOKING
BACK
|
My first publication; and actually the reason why
I started learning C. At the end of all the struggles with arrays and pointers etc. I was
pretty fit in C. ;-) It would not remain my last C program... |
