usage: cairo-trace [--no-file|--verbose] command
|
|
cairo-trace will generate a log of all calls made by command to
|
|
cairo. This log will be stored in a file in the local directory
|
|
called command.pid.trace.
|
|
Whatever else happens is driven by its argument:
|
|
--flush - Flush the output trace after every call.
|
|
--verbose - Show the trace on stdout.
|
|
--no-file - Disable the creation of an output file.
|
|
--no-callers - Do not lookup the caller address/symbol/line whilst tracing.
|
|
|
|
Enviroment variables understood by cairo-trace:
|
|
CAIRO_TRACE_FLUSH - flush the output after every function call.
|
|
CAIRO_TRACE_LINE_INFO - emit line information for most function calls.
