I could take down 2000 easily enough.	by Avium	2003-01-13 19:40:19
I had to by pass the printer drivers on windows to send certian escape sequences to the printers. The API call to get a spooler file requires a 'lpsz' or long pointer to a null terminated string as part of the structure. Me being the nice guy that I am allocated the printer structure with a pointer to a 256 char array for windows to put the file name into. This program would always trash the system. Debugging was rather annoying...Run. Reboot. Change code. Run. Reboot. ... This was a complicated routine so the lpsz was one of the last things I checked. When I finally checked the memory location I found something interesting. The valid pointer which I correctly allocated was being wiped out with an invalid one which constantly pointed to the same location. The four bytes that wiped out my valid pointer were always : 0x43, 0x3a, 0x5c, 0x57. In other words : 'C:\W'. Wonderful API documentation.
