NAME

seek - change file offset

SYNOPSIS

#include <u.h>
#include <libc.h>

vlong seek(int fd, vlong n, int type)

DESCRIPTION

Seek sets the offset for the file associated with fd as follows:

If type is 0, the offset is set to n bytes.

If type is 1, the pointer is set to its current location plus n.

If type is 2, the pointer is set to the size of the file plus n.

The new file offset value is returned.

Seeking in a directory is not allowed. Seeking in a pipe is a no-op.
