I freely admit that this is basically a newbie type question (despite the
mainframe gray hairs I have earned).
Based on advice on another thread I am now calling errno2() on certain
socket errors. I get back an integer that I dutifully display in hex:
XXX0123I errno2 = x'12345678'. Look up using BPXMTEXT.
That message kind of offends me. When I get a basic library error I use
strerror() to convert it to text. I would like to convert errno2() to text,
rather than telling customers to go look it up for themselves.
If I wanted to call BPXMTEXT from within my program and capture the text
output, what would I to do? I'm sure I could solve this with enough
experimentation but the gray hairs have made me impatient.
Something like system("bpxmtext %x") where I substitute the errno2() value
into the message. But (1) I read a warning about having to allocate stdin
and so forth, and (2) I would like to capture the output. I suspect those
two issues have the same solution, and perhaps someone could point me in the
right direction?
Environment is started task, POSIX(ON), C++, any current release of z/OS.
Thanks,
Charles
