sysseek

Synopsis

sysseek filehandle, offset, whence

Description

A variant of seek() that sets and gets the file’s system read/write position using the lseek(2) system call. It’s the only reliable way to seek before a sysread() or syswrite(). Returns the new position, or undef on failure. Arguments are the same as for seek.
