HISTORY
glibc 2.1.
lseek64()
is one of the functions that was specified in the Large File Summit (LFS)
specification that was completed in 1996.
The purpose of the specification was to provide transitional support
that allowed applications on 3-bit systems to access
files whose size exceeds that which can be represented with a 3-bit
off_t
type.
