.\" @(#)fclose.3s 6.1 (Berkeley) 5/15/85 .\" .TH FCLOSE 3 "May 15, 1985" .AT 3 .SH NAME fclose, fflush \- close or flush a stream .SH SYNOPSIS .nf .ft B #include int fclose(FILE *\fIstream\fP) int fflush(FILE *\fIstream\fP) .ft R .fi .SH DESCRIPTION .B Fclose causes any buffers for the named .I stream to be emptied, and the file to be closed. Buffers allocated by the standard input/output system are freed. .PP .B Fclose is performed automatically upon calling .BR exit (3). .PP .B Fflush causes any buffered data for the named output .I stream to be written to that file. The stream remains open. .SH "SEE ALSO" .BR close (2), .BR fopen (3), .BR setbuf (3). .SH DIAGNOSTICS These routines return .SM .B EOF if .I stream is not associated with an output file, or if buffered data cannot be transferred to that file.
