SYS-SEEK(2) SYS-SEEK(2) NAME seek - change file offset SYNOPSIS include "sys.m"; sys := load Sys Sys->PATH; seek: fn(fd: ref FD, off: big, start: int): big; DESCRIPTION Seek sets the 64-bit offset for the file associated with fd as follows: If start is Sys->SEEKSTART, the offset is set to off bytes. If start is Sys->SEEKRELA, the pointer is set to its current location plus off. If start is Sys->SEEKEND, the pointer is set to the size of the file plus off. The new file offset value is returned. Seeking in a pipe is not allowed. Seeking in a directory is allowed only if the new offset is zero. SEE ALSO sys-intro(2), sys-open(2), bufio(2), Page 1 Plan 9 (printed 9/8/24)
