The width of this data type must remain * constant and independent of any possible large file support settings. * * As an exception to the above, curl_off_t shall be typedef'ed to a 32-bit * wide signed integral data type if there is no 64-bit type. * * As a general rule, curl_off_t shall not be mapped to off_t. This rule shall * only be violated if off_t is the only 64-bit data type available and the * size of off_t is independent of large file support settings. Keep your * build on the safe side avoiding an off_t gating. If you have a 64-bit * off_t then take for sure that another 64-bit data type exists, dig deeper * and you will find it. * */ #if defined(__DJGPP__) || defined(__GO32__) # if defined(__DJGPP__) && (__DJGPP__ > 1) #
