.ig @(#)close.2 2.1 7/1/84 @(#)Copyright (C) 1983 by National Semiconductor Corp. .. .TH CLOSE 2 .UC 4 .SH NAME close \- close a file .SH SYNOPSIS .B close(fildes) .SH DESCRIPTION Given a file descriptor such as returned from an .I open, .I creat, .I dup or .IR pipe (2) call, .I close closes the associated file. A close of all files is automatic on .I exit, but since there is a limit on the number of open files per process, .I close is necessary for programs which deal with many files. .PP Files are closed upon termination of a process, and certain high-numbered file descriptors are closed by .IR exec (2), and it is possible to arrange for others to be closed (see FIOCLEX in .IR ioctl (2)). .SH "SEE ALSO" creat(2), open(2), pipe(2), exec(2), ioctl(2) .SH DIAGNOSTICS Zero is returned if a file is closed; \-1 is returned for an unknown file descriptor.
