Im trying to use fseeko64. It works perfectly when using positive offsets, but whenever i use a negative offset something strange happens and my program creates huge files (after+/- 15 secs and 2.5GB data i killed my program)
Am i doing something wrong? Cant fseeko64 be used with negative values?
Im on winxp with mingw compiler
Sry for the title-edit
this is really weird stuff. fseeko64 DOES work, the values i pass to it are wrong:
Why does os64 = -sizeof(int) doesnt work?Code:off64_t os64; os64 = sizeof(int); os64 = -os64; // works os64 = -sizeof(int); // os64 gets a VERY big value
