POP3MessageCount (socket[,stsproc]) Returns messagecount
Note: The flag is set according to whether Omnis was able to make a call to this external command.
This Web command is multi-threaded, allowing another thread to execute in the multi-threaded server while it runs. Note that the same socket cannot safely be used concurrently by more than one thread.
POP3MessageCount returns the count of messages available on a POP3 server. The count includes messages marked for deletion (see POP3DeleteMessage).
Socket is an Omnis Long Integer field containing a socket opened to a POP3 server using POP3Connect.
StsProc is an optional parameter containing the name of an Omnis method that POP3MessageCount calls with status messages. POP3MessageCount calls the method with no parameters, and the status information in the variable #S1. The status information logs protocol messages exchanged on the connection to the server.
MessageCount is an Omnis Long Integer field which receives the number of messages. If an error occurs, the returned value is an error code with a value less than zero. Possible error codes are listed in the Web Command Error Codes Appendix.
# Find out how many messages exist on the POP3 server lServer
# for user lUserName
Calculate lServer as 'my.pop3.server'
Calculate lUserName as 'myusername'
Calculate lPassword as 'mypassword'
POP3Connect (lServer,lUserName,lPassword) Returns iSocket
POP3MessageCount (iSocket) Returns lMessageCount
