I originally focused on system() as the way to run BPXMTEXT and the doc for
system() says
Note: If an application invokes a z/OS UNIX service shell command or utility
that
performs terminal I/O, the command may fail due to the z/OS UNIX services
shell file descriptors not being initialized. z/OS UNIX files for terminal
I/O must
be defined. An example of how these can be defined in a C application are as
follows:
stdin = fopen("/tmp/sys.stdin","r");
stdout = fopen("/tmp/sys.stdout","w");
stderr = fopen("/tmp/sys.stderr","w");
"An example ... are ..." Oh, well.

Where is that warning? In Doc? Or did it occur as an error message?
Why should bpxmtext need stdin?
