I have some code. I need to be able to loop it and then break out of it.
Basically, if the message subject is blank, it should execute the apply command until the message subject isn't blank. I'm rather new to C, so please excuse my ignorance. MSG_SUBJECT[0] == 0 is a blank subject. dd_docmd(d, "apply"); tells the BBS to run the apply command.
header.MSG_SUBJECT[0] only occurs in the source code once, so I don't know how to determine what a different value than == 0 means. I had assumed that a value of == 1 meant a non blank subject, but apparently I was wrong. Anyway, if someone could help a newbie out, i'd appreciate it.



if (header.MSG_SUBJECT[0] == 0) 
dd_docmd(d, "apply");
return(0);



Thanks.
