This change adds rtems_printf and related functions and wraps the
RTEMS print plugin support into a user API. All references to the
plugin are removed and replaced with the rtems_printer interface.
Printk and related functions are made to return a valid number of
characters formatted and output.
The function attribute to check printf functions has been added
to rtems_printf and printk. No changes to remove warrnings are part
of this patch set.
The testsuite has been moved over to the rtems_printer. The testsuite
has a mix of rtems_printer access and direct print control via the
tmacros.h header file. The support for begink/endk has been removed
as it served no purpose and only confused the code base. The testsuite
has not been refactored to use rtems_printf. This is future work.
This directory contains a shell user extension
primary features:
+ create a user shell terminal task.
This code has not been extensively tested. It is provided as a tool
for RTEMS users to open more shell terminal.
Suggestions and comments are appreciated.
NOTES:
1. printf() & getchar() works but you can't use
0,1,2 like fildes. You need to use fileno(stdin),fileno(stdout),...
2. You only need a termios dev to start a new session, add your new commands
and enjoy it.
3. Telnetd daemon uses this (browse libnetworking/rtems_telnetd)
Enjoy it.
FUTURE:
1. Adding new commands in cmds.c to give file manegement to shell.
