I am fairly new to Cygwin (occasionally using an old version) but I now need to write a program which can fseek() through very large AVI files (12 GB or even larger). I believe that large file support is in version 1.5.0 of Cygwin but can't find any details of how to use it. Are there separate 64-bit versions of fopen/fseek/... called fopen64/fseek64 as on some platforms, or is there some sort of "transparent" support where you can continue to use fopen/fclose? And what is the integer type you need to pass into fseek/fseek64 to specify 64-bit file offsets? Thanks Colin __________________________________ Do you Yahoo!? Yahoo!
