close − close a file
close(fildes)
Given a file descriptor such as returned from an open, creat, dup or pipe(2) call, close closes the associated file. A close of all files is automatic on exit, but since there is a limit on the number of open files per process, close is necessary for programs which deal with many files.
Files are closed upon termination of a process, and certain file descriptors may be closed by exec(2) (see ioctl(2)).
creat(2), open(2), pipe(2), exec(2), ioctl(2)
Zero is returned if a file is closed; −1 is returned for an unknown file descriptor.
(close = 6.)
