| 75 ** FUNCTION: PR_Select | |
| 76 ** DESCRIPTION: | |
| 77 ** | |
| 78 ** The call returns as soon as I/O is ready on one or more of the underlying | |
| 79 ** file/socket descriptors or an exceptional condition is pending. A count of th
e | |
| 80 ** number of ready descriptors is returned unless a timeout occurs in which case
| |
| 81 ** zero is returned. On return, PR_Select replaces the given descriptor sets wi
th | |
| 82 ** subsets consisting of those descriptors that are ready for the requested cond
ition. | |
| 83 ** The total number of ready descriptors in all the sets is the return value. | |
| 84 ** | |
| 85 ** INPUTS: | |
| 86 ** PRInt32 num | |
| 87 ** This argument is unused but is provided for select(unix) interface | |
| 88 ** compatability. All input PR_fd_set arguments are self-describing | |
| 89 ** with its own maximum number of elements in the set. | |
| 90 ** | |
| 91 ** PR_fd_set *readfds | |
| 92 ** A set describing the io descriptors for which ready for reading | |
| 93 ** condition is of interest. | |
| 94 ** | |
| 95 ** PR_fd_set *writefds | |
| 96 ** A set describing the io descriptors for which ready for writing | |
| 97 ** condition is of interest. | |
| 98 ** | |
| 99 ** PR_fd_set *exceptfds | |
| 100 ** A set describing the io descriptors for which exception pending | |
| 101 ** condition is of interest. | |
| 102 ** | |
| 103 ** Any of the above readfds, writefds or exceptfds may be given as NULL | |
| 104 ** pointers if no descriptors are of interest for that particular condition.
| |
| 105 ** | |
| 106 ** PRIntervalTime timeout | |
| 107 ** Amount of time the call will block waiting for I/O to become ready. | |
| 108 ** If this time expires without any I/O becoming ready, the result will | |
| 109 ** be zero. | |
| 110 ** | |
| 111 ** OUTPUTS: | |
| 112 ** PR_fd_set *readfds | |
| 113 ** A set describing the io descriptors which are ready for reading. | |
| 114 ** | |
| 115 ** PR_fd_set *writefds | |
| 116 ** A set describing the io descriptors which are ready for writing. | |
| 117 ** | |
| 118 ** PR_fd_set *exceptfds | |
| 119 ** A set describing the io descriptors which have pending exception. | |
| 120 ** | |
| 121 ** RETURN:PRInt32 | |
| 122 ** Number of io descriptors with asked for conditions or zero if the function | |
| 123 ** timed out or -1 on failure. The reason for the failure is obtained by | |
| 124 ** calling PR_GetError(). | |
| 125 ** XXX can we implement this on windoze and mac? | |
