ARES_INIT(3) Library Functions Manual ARES_INIT(3) NAME ares_init - Initialize a resolver channel SYNOPSIS #include <ares.h> int ares_init(ares_channel *channelptr) DESCRIPTION The ares_init(3) function initializes a communications channel for name service lookups. If it returns successfully, ares_init(3) will set the variable pointed to by channelptr to a handle used to identify the name service channel. The caller should invoke ares_destroy(3) on the han- dle when the channel is no longer needed. The ares_init_options(3) function is provide to offer more init alter- natives. RETURN VALUES ares_init(3) can return any of the following values: ARES_SUCCESS Initialization succeeded. ARES_EFILE A configuration file could not be read. ARES_ENOMEM The process's available memory was exhausted. ARES_ENOTINITIALIZED c-ares library initialization not yet performed. ATTRIBUTES See attributes(7) for descriptions of the following attributes: +---------------+------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+------------------+ |Availability | library/libcares | +---------------+------------------+ |Stability | Volatile | +---------------+------------------+ NOTES When initializing from /etc/resolv.conf, ares_init(3) reads the domain and search directives to allow lookups of short names relative to the domains specified. The domain and search directives override one another. If more that one instance of either domain or search direc- tives is specified, the last occurrence wins.
