 | | On most pre-POSIX systems, the constants used with lseek are called L_SET, L_INCR, and L_XTND. On even older UNIX systems, no constants are defined at all. The integers 0, 1, and 2 are used instead. In either case, you can replace them with the POSIX constants SEEK_SET, SEEK_CUR, and SEEK_END, respectively. | |
