Update.
2002-11-05 Ulrich Drepper <drepper@redhat.com> * libio/ioseekoff.c: Remove INTDEF. Define _IO_seekoff_unlocked. Same as old code without locking. _IO_seekoff calls this function after locking the stream. * libio/ioseekpos.c: Likewise for _IO_seekpos. * libio/libioP.h: Replace _IO_seekoff_internal and _IO_seekpos_internal prototypes with _IO_seekoff_unlocked and _IO_seekpos_unlocked prototypes. * libio/iolibio.h (_IO_fseek): Call _IO_seekoff_unlocked instead of _IO_seekoff_internal. (_IO_rewind): Likewise. * libio/ioftell.c: Likewise. * libio/ftello.c: Likewise. * libio/ftello64.c: Likewise. * libio/iofgetpos.c: Likewise. * libio/iofgetpos64.c: Likewise. * libio/oldiofgetpos.c: Likewise. * libio/oldiofgetpos64.c: Likewise. * libio/iofsetpos.c: Call _IO_seekpos_unlocked instead of _IO_seekpos_internal. * libio/iofsetpos64.c: Likewise. * libio/oldiofsetpos.c: Likewise. * libio/oldiofsetpos64.c: Likewise. * libio/wfileops.c (_IO_wfile_seekoff): Don't modify _offset and _wide_data->_IO_read_end if adjustment can be made in the current buffer.

as old code without locking. _IO_seekoff calls this function after

locking the stream.

* libio/libioP.h: Replace _IO_seekoff_internal and _IO_seekpos_internal

prototypes with _IO_seekoff_unlocked and _IO_seekpos_unlocked

prototypes.

* libio/iolibio.h (_IO_fseek): Call _IO_seekoff_unlocked instead
|
||||
of _IO_seekoff_internal.

(_IO_rewind): Likewise.
