Hi Urgent
Hi
Im launching another applicaTION from my "C" program.
Is there any way to capture the application output only.
Example.
printf ("U have pressed 1\n");
system("ls -l");
printf (" U have launched a command\n");
Any way to capture only output from the system ("ls -l") command.
Other 2 printf statements should be print on the terminal.

evtest-capture
EVTEST-CAPTURE(1) EVTEST-CAPTURE(1)
NAME
evtest-capture - Input device event capture program
SYNOPSIS
evtest-capture "/dev/input/eventX" [evtest-capture.xml]
DESCRIPTION
evtest-capture captures the information and events from the input device specified on the command line and writes it to the xml file given.
If no filename is given for the output file, evtest-capture.xml is chosen as default.
evtest-capture needs to be able to read from the device; in most cases this means it must be run as root.
Together with with evtest-create-device.xsl, a simple uinput-based software input device can be created that replays the events as if the
same input was performed on the physical device. This can be useful to replicate bugs with input devices in upper layers of the stack.
To convert evtest-capture.xml into such a uinput device, run:
xsltproc evtest-create-device.xls evtest-capture.xml > mydevice.c
gcc -o mydevice mydevice.c
./mydevice
DIAGNOSTICS
If evtest-capture does not see any events even though the device is being used, the device may be grabbed by a process (EVIOCGRAB). This is
usually the case when debugging a synaptics device from within X. VT switching to a TTY or shutting down the X server terminates this grab
and synaptics devices can be debugged.
