ares_set_sortlist - Initialize an ares_channel sortlist configuration
#include <ares.h> int ares_set_sortlist(ares_channel channel, const char *sortstr)
The ares_set_sortlist(3) function initializes an address sortlist configuration for the channel data identified by channel, so that addresses returned by ares_gethostbyname(3) are sorted according to the sortlist. The provided sortstr string that holds a space separated list of IP-address-netmask pairs. The netmask is optional but follows the address after a slash if present. For example, "126.96.36.199/255.255.240.0 188.8.131.52". This function replaces any potentially previously configured address sortlist with the ones given in the configuration string.
ares_set_sortlist(3) may return any of the following values: ARES_SUCCESS The sortlist configuration was successfully initialized. ARES_ENOMEM The process's available memory was exhausted. ARES_ENODATA The channel data identified by channel was invalid. ARES_ENOTINITIALIZED c-ares library initialization not yet performed.
ares_set_sortlist(3) was added in c-ares 1.11.0 23 November 2015 ARES_SET_SORTLIST(3)
