Home: Perl Programming Help: Advanced: specifications of sys(\w+) functions

krcrouse New User Mar 17, 2002, 11:50 AM Post #1 of 2 (1538 views) specifications of sys(\w+) functions Can't Post Hey folks- I am interested in the sys__ functions (sysopen, sysread, etc) and their implementation. How do, if at all, the sys__ functions cache the disk page? >> say my page size is 40k and I want to read from a certain byte. does it buffer the 40k starting at that byte, ending at that byte, middling that byte, &c? If anyone could give me any other information on how they work, I would appreciate it. thanks! -kevin

After all (AFAIK) the functions are only the interface to the OS's FS functions.
