dlv trace

Compile and begin tracing program.

Synopsis

Trace program execution.

The trace sub command will set a tracepoint on every function matching the provided regular expression and output information when tracepoint is hit. This is useful if you do not want to begin an entire debug session, but merely want to know what functions your process is executing.

The output of the trace sub command is printed to stderr, so if you would like to only see the output of the trace operations you can redirect stdout.
