closeOut -- close an output file

Description

f << closeOut -- closes the output file f.
closeOut f -- closes the output file f.

Any buffered output is first written to the file, and the return value is an integer, normally 0, or -1 on error, or the return status of the child process in case the file was a pipe.

If the file was open only for output, then close is easier to use and has the same effect.

If the file was open for both input and output, it remains open for input.
