For I/O redirection to work a source file must include epicsStdioRedirect.h.
This sucks.
It this is the case, I would say that there is something wrong with the
EPICS redirection. Code should not need to know about its "environment".
This contradicts any good programming practice.

It's likely that lots of support modules and drivers have not yet done so.

Hello,
When using redirection of output to a file in iocshCmd where the command is one that calls report functions via function pointer like dbior:
iocshCmd("dbior > /dat/dbiorOutput")
the output file contains only the output (printf) from the dbior routine itself but not output (printf) from each driver (called using a function pointer in drvet).
Is this a limitation of the iocsh, mixing C and C++, or the non-thread-safeness (as advertised in the app dev guide) of iocshCmd? Or am I doing something else wrong? It happens on linux-x86_64, RTEMS 4.9.4, and vxWorks 5.4.
Thank you,
Stephanie Allison
