7896 | This routine is called by the SIGIO handler. |
7897 | We return as soon as there are no more events to be read. | |
7898 | ||
7899 | Events representing keys are stored in buffer BUFP, | |
7900 | which can hold up to NUMCHARS characters. | |
7901 | We return the number of characters stored into the buffer, | |
7902 | thus pretending to be `read'. | |
7903 | ||
ee78dc32 GV |
7904 | EXPECTED is nonzero if the caller knows input is available. |
7905 | ||
7906 | Some of these messages are reposted back to the message queue since the | |
e9e23e23 GV |
7907 | system calls the windows proc directly in a context where we cannot return |
7908 | the data nor can we guarantee the state we are in. So if we dispatch them | |
ee78dc32 GV |
7909 | we will get into an infinite loop. To prevent this from ever happening we |
7910 | will set a variable to indicate we are in the read_socket call and indicate | |
e9e23e23 GV |
7911 | which message we are processing since the windows proc gets called |
7912 | recursively with different messages by the system. | |
