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.

PCAP_SET_TSTAMP_TYPE(3PCAP)PCAP_SET_TSTAMP_TYPE(3PCAP)NAME
pcap_set_tstamp_type - set the time stamp type to be used by a capture device
SYNOPSIS
#include <pcap/pcap.h>
int pcap_set_tstamp_type(pcap_t *p, int tstamp_type);
DESCRIPTION
pcap_set_tstamp_type() sets the the type of time stamp desired for packets captured on the pcap descriptor to the type specified by
tstamp_type. It must be called on a pcap descriptor created by pcap_create() that has not yet been activated by pcap_activate().
pcap_list_tstamp_types() will give a list of the time stamp types supported by a given capture device. See pcap-tstamp(7) for a list of
all the time stamp types.
RETURN VALUE
pcap_set_tstamp_type() returns 0 on success if the specified time stamp type is expected to be supported by the capture device, PCAP_WARN-
ING_TSTAMP_TYPE_NOTSUP on success if the specified time stamp type is not supported by the capture device, PCAP_ERROR_ACTIVATED if called
on a capture handle that has been activated, and PCAP_ERROR_CANTSET_TSTAMP_TYPE if the capture device doesn't support setting the time
stamp type.

I was wondering is there something out there for Solaris 7 for screen capture?
Also it would really help if there was some software out there that can record whats happens on the screen for like 10 seconds or how ever long I need it to.

Can i do the replacement in the same command?
Thanks a lot.
