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
       _F_c_l_o_s_e  causes  any buffers for the named _s_t_r_e_a_m to be emptied, and the
       file to be closed.  Buffers allocated by the standard input/output sys‐
       tem are freed.

       _F_c_l_o_s_e is performed automatically upon calling _e_x_i_t(3).

       _F_f_l_u_s_h causes any buffered data for the named output _s_t_r_e_a_m to be writ‐
       ten to that file.  The stream remains open.

SEE ALSO
       close(2), fopen(3S), setbuf(3S)

DIAGNOSTICS
       These routines return EOF if _s_t_r_e_a_m is not associated  with  an  output
       file, or if buffered data cannot be transferred to that file.
