.SH NAME

.SH SYNOPSIS

|
.SH DESCRIPTION
|
|
|
|
.B weston-debug
|
|
is a debugging tool which uses weston_debug_v1 interface to get the
|
|
debug messages from the compositor. The debug messages are categorized into different
|
|
debug streams by the compositor (example: logs, proto, list, etc.,) and the compositor
|
|
requires a file descriptor to stream the messages.
|
|
|
|
This tool accepts a file name or a file descriptor (not both) and any desired debug stream
|
|
names from the user as command line arguments and subscribes the desired streams from the
|
|
compositor by using the weston_debug_v1 interface. After the subscription, the
|
|
compositor will start to write the debug messages to the shared file descriptor.
|
|
|
|
If no file name or file descriptor argument is given, the tool will use the stdout file
|
|
descriptor.
