_mmmm_kkkk_ffff_iiii_ffff_oooo creates the FIFO special files named by its argument list. The
arguments are taken sequentially, in the order specified; and each FIFO
special file is either created completely or, in the case of an error or
signal, not created at all.
For each _p_a_t_h argument, the _mmmm_kkkk_ffff_iiii_ffff_oooo command behaves as if the function
_mmmm_kkkk_ffff_iiii_ffff_oooo [see _mmmm_kkkk_ffff_iiii_ffff_oooo(2)] was called with the argument _p_a_t_h set to _p_a_t_h and
the _m_o_d_e set to the bitwise inclusive OR of _SSSS______IIII_RRRR_UUUU_SSSS_RRRR, _SSSS______IIII_WWWW_UUUU_SSSS_RRRR, _SSSS______IIII_RRRR_GGGG_RRRR_PPPP,
_SSSS______IIII_WWWW_GGGG_RRRR_PPPP, _SSSS______IIII_RRRR_OOOO_TTTT_HHHH and _SSSS______IIII_WWWW_OOOO_TTTT_HHHH.
If _----_mmmm option is specified, the file permission bits of the newly created
FIFO is set to the specified _m_o_d_e value. The _m_o_d_e option argument is the
same as the _m_o_d_e operand defined for the _cccc_hhhh_mmmm_oooo_dddd utility. In the
_s_y_m_b_o_l_i_c__m_o_d_e strings, the _o_p characters ++++ and ---- are interpreted relative
to an assumed initial mode of a=rw.
If errors are encountered in creating one of the special files, _mmmm_kkkk_ffff_iiii_ffff_oooo
writes a diagnostic message to the standard error and continues with the
remaining arguments, if any.

_mmmm_kkkk_ffff_iiii_ffff_oooo returns exit code _0000 if all FIFO special files were created
normally; otherwise it prints a diagnostic and returns a value greater
