The argument fildes must be an open + file descriptor. Lseek repositions the file pointer + fildes as follows: + + If whence is SEEK_SET, the offset is set to offset + bytes. + + If whence is SEEK_CUR, the offset is set to its + current location plus offset bytes. + + If whence is SEEK_END, the offset is set to the + size of the file plus offset bytes. + + The lseek function allows the file offset to be set beyond + the end of the existing end-of-file of the file. If data + is later written at this point, subsequent reads of the + data in the gap return bytes of zeros (until data is actu- + ally written into the gap). + + Some devices are incapable of seeking. The value of the + pointer associated with such a device is undefined. + +<h3>RETURN VALUES +</h3> Upon successful completion, lseek returns the resulting + offset location as measured in bytes from the beginning of + the file. Otherwise, a value of -1 is returned and errno + is set to indicate the error. + +<h3>ERRORS +</h3> EBADF Fildes is not an open file descriptor. + + ESPIPE Fildes is associated with a pipe, socket, or FIFO. + + EINVAL Whence is not a proper value. + +<h3>CONFORMS TO +</h3> POSIX, BSD 4.3 + +<h3>BUGS +</h3> This document's use of whence is incorrect English, but + maintained for historical reasons. + + + + + +<h3>Linux 1.2.9 10 June 1995 1 +</h3> + + + + +<h3>LSEEK(2) Linux Programmer's Manual LSEEK(2) +</h3> + +</pre> +<hr> +<h3>SEE ALSO +</h3><p> +<a href=dup.htm>dup</a>, +<a href=open.htm>open</a>, +<a href=fseek.htm>fseek</a>, +<pre> + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +<h3>Linux 1.2.9 10 June 1995 2 +</h3> + +
