CLOSE(2)            UNIX Programmer's Manual             CLOSE(2)

NAME
     close  -  close a file

SYNOPSIS
     close(fildes)

DESCRIPTION
     Given a file descriptor such as returned from an _o_p_e_n,
     _c_r_e_a_t, _d_u_p or _p_i_p_e(2) call, _c_l_o_s_e closes the associated
     file.  A close of all files is automatic on _e_x_i_t, but since
     there is a limit on the number of open files per process,
     _c_l_o_s_e 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 _e_x_e_c_v_e(2) (see _i_o_c_t_l(2)).

RETURN VALUE
     Upon successful completion, a value of 0 is returned.  Oth-
     erwise, a value of -1 is returned and _e_r_r_n_o is set to indi-
     cate the error.

ERRORS
     _C_l_o_s_e will fail if:

     [EBADF]             _F_i_l_d_e_s is not an active descriptor.
