Re: How to properly end a C program using stdio with F3

Hello,

I have ported a self-written C program to my AS/400 (yes, AS/400,
9401-150, running V4R5). The program is looping over recvfrom() to receive
data from an UDP socket. If data is received, the program outputs parsed
data via printf() to stdout for debugging purposes. In practice, the number
of packets received is less than five per second. Runs fine, does stuff
like expected. So far so good.

I can't end this program with F3 in the "fake terminal". The keyboard gets
locked (like the AS/400 does when it's busy) and thus doesn't accept any
keys. Even pressing reset and immediately F3 yields no program ending: The
keyboard gets locked again.

I read the two Unix porting guides:
- UNIX C Applications Porting to AS/400 Companion Guide.pdf
- UNIX C Applications Porting to AS/400.pdf

But I haven't found any mentioning how to handle a similar situation. I
also browsed through the ILE C/C++ Programmer's Guide.pdf, with also no
helpful findings.

May I kindly ask for advice? Thanks!
