(Only valid with aaaassssddddffffllllttttsssseeeerrrrvvvveeeerrrroooopppptttt). Retrieves the hostname of the
default array services daemon. This value is obtained from the
environment variable _AAAA_RRRR_RRRR_AAAA_YYYY_DDDD if it exists, otherwise "localhost" is
used.
The parameters _O_p_t_V_a_l and _O_p_t_L_e_n are used to access option values for
aaaasssssssseeeettttsssseeeerrrrvvvveeeerrrroooopppptttt. For aaaassssggggeeeettttsssseeeerrrrvvvveeeerrrroooopppptttt and aaaassssddddffffllllttttsssseeeerrrrvvvveeeerrrroooopppptttt, they identify a
buffer in which the value for the requested option is to be returned.
For those functions, _O_p_t_L_e_n is a value-result parameter, initially
containing the size in bytes of the buffer pointed to by _O_p_t_V_a_l, and
modified on return to indicate the actual size of the value returned.
If any of these functions is unsuccessful, -1 is returned and
_a_s_e_r_r_o_r_c_o_d_e(3X) will be set appropriately.

These functions are found in the library "libarray.so", and will be
loaded if the option "-larray" is used with _c_c(1) or _l_d(1).
