AIX的poll用法

anthony1983

好像和其他平台的poll用法不同，man手册如下，有用过的兄弟给个例子？


struct pollist {

   struct pollfd fds[3];

   struct pollmsg msgs[2];

   } list;

The structure can then be initialized as follows:

list.fds[0].fd = file_descriptorA;

list.fds[0].events = requested_events;

list.msgs[0].msgid = message_id;

list.msgs[0].events = requested_events;

The rest of the elements in thefdsandmsgsarrays can be initialized the same way.
The poll subroutine can then be called, as follows:

nfds = 3;   /* number of pollfd structs */

nmsgs = 2;   /* number of pollmsg structs */

timeout = 1000   /* number of milliseconds to timeout */

poll(&list, (nmsgs<<16)|(nfds), 1000);
