FCLOSE(3S) FCLOSE(3S) NAME fclose, fflush - close or flush a stream SYNOPSIS #include <stdio.h> fclose(stream) FILE *stream; fflush(stream) FILE *stream; DESCRIPTION Fclose causes any buffers for the named stream to be emp- tied, and the file to be closed. Buffers allocated by the standard input/output system are freed. Fclose is performed automatically upon calling exit(2). Fflush causes any buffered data for the named output stream to be written to that file. The stream remains open. SEE ALSO close(2), fopen(3), setbuf(3) DIAGNOSTICS These routines return EOF if stream is not associated with an output file, or if buffered data cannot be transferred to that file.
