Re: list of open descriptors

[Vernon Hamberg <vhamberg@xxxxxxxxxxxxxxx>]

Hi Mike

Did a little looking and wonder if the fcntl() function will do the 
trick. You'd need to do a loop until it returns an error - that'd be the 
first available descriptor.

You could use a read function in fcntl() - something like 
fcntl(descriptor : 1) in RPG - both are integers passed by value. If you 
get a -1 returned, that's an error.

This is just a guess - hope there's a better answer, maybe in an MI 
function.

In particular, these are the descriptors to write to IFS files but my understanding is that descriptors can be for any "open" operation such as a socket as well.
