Since one can add a #define to allow using buffered IO (fread, fwrite, etc) for files in excess of 2 gigabytes. then this define should be permanent within stdio.h . I wanted to read an ISO DVD and could not. I would refer the owner of this maintenance problem to the actual libc.pdf file section 4.17, which makes no mention of the #define. (However in respoonse to Andreas Jaeger, personal reply (which I appreciate receiving and for which I thank him), using the search of the libc.PDF I did find a chapter about large file support. Something is wrong when today a large file is one measured in petabytes. Please redirect this topic and this bug to the documentation project and of course to a steering committee to update the stream IO functionality to handle very large files, or to state that in the libc.pdf fopen() document, to refer to the large file section. I lost quite a few hours of digging to independently discoover the #define that enables large file support. I would also ask why large file support is turned on for 64 bit linux? Had 64 bit linux the same constraint, I would have not been concerned. (I was porting code from 64bit to 32bit), for older systems. Thank you again Andreas, for the prompt reply. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
