ARES_FDS(3) Library Functions Manual ARES_FDS(3) NAME ares_fds - return file descriptors to select on SYNOPSIS #include <ares.h> int ares_fds(ares_channel channel, fd_set *read_fds, fd_set *write_fds) DESCRIPTION The ares_fds(3) function retrieves the set of file descriptors which the calling application should select on for reading and writing for the processing of name service queries pending on the name service channel identified by channel. File descriptors will be set in the file descriptor sets pointed to by read_fds and write_fds as appropriate. File descriptors already set in read_fds and write_fds will remain set; initialization of the file descriptor sets (using FD_ZERO) is the responsibility of the caller. RETURN VALUES ares_fds(3) returns a value that is one greater than the number of the highest socket set in either read_fds or write_fds. If no queries are active, ares_fds(3) returns 0.
