+
+DESCRIPTION
+These functions provides access to the internals of the FILE structure <[fp]>.
+
+RETURNS
+<<__fbufsize>> returns the number of bytes in the buffer of stream <[fp]>.
+
+<<__fpending>> returns the number of bytes in the output buffer of stream <[fp]>.
+
+<<__flbf>> returns nonzero if stream <[fp]> is line-buffered, and <<0>> if not.
+
+<<__freadable>> returns nonzero if stream <[fp]> may be read, and <<0>> if not.
+
+<<__fwritable>> returns nonzero if stream <[fp]> may be written, and <<0>> if not.
+
+<<__freading>> returns nonzero if stream <[fp]> if the last operation on
+it was a read, or if it read-only, and <<0>> if not.
+
+<<__fwriting>> returns nonzero if stream <[fp]> if the last operation on
+it was a write, or if it write-only, and <<0>> if not.
+
+PORTABILITY
+These functions originate from Solaris and are also provided by GNU libc.
+
+No supporting OS subroutines are required.
