From 670273968ce2a8e648c61829d3304de23d91349d Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Wed, 30 May 2007 12:58:47 +0000 Subject: added ares_process_fd() to allow applications to ask for processing on specific sockets and thus avoiding select() and associated functions/macros. This function will be used by upcoming libcurl releases for this very reason. It also made me export the ares_socket_t type in the public ares.h header file, since ares_process_fd() uses that type for two of the arguments. --- ares/ares.h | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) (limited to 'ares/ares.h') diff --git a/ares/ares.h b/ares/ares.h index 83a1c8e46..73fc3e6c3 100644 --- a/ares/ares.h +++ b/ares/ares.h @@ -136,6 +136,22 @@ extern "C" { #define ARES_GETSOCK_WRITABLE(bits,num) (bits & (1 << ((num) + \ ARES_GETSOCK_MAXNUM))) + +/* + * Typedef our socket type + */ + +#ifndef ares_socket_typedef +#ifdef WIN32 +typedef SOCKET ares_socket_t; +#define ARES_SOCKET_BAD INVALID_SOCKET +#else +typedef int ares_socket_t; +#define ARES_SOCKET_BAD -1 +#endif +#define ares_socket_typedef +#endif /* ares_socket_typedef */ + #ifdef WIN32 typedef void (*ares_sock_state_cb)(void *data, SOCKET socket, @@ -200,6 +216,8 @@ int ares_getsock(ares_channel channel, int *socks, int numsocks); struct timeval *ares_timeout(ares_channel channel, struct timeval *maxtv, struct timeval *tv); void ares_process(ares_channel channel, fd_set *read_fds, fd_set *write_fds); +void ares_process_fd(ares_channel channel, ares_socket_t read_fd, + ares_socket_t write_fd); int ares_mkquery(const char *name, int dnsclass, int type, unsigned short id, int rd, unsigned char **buf, int *buflen); -- cgit v1.2.3
