Subject: iocshCmd, redirection, and function pointers

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

Here is dbior done at the ioc prompt and one redirected to a testing file.  The testing file doesn't get any detail:
