Description:
LTTng 2.0 Userspace Tracer (development files)
The userspace tracer is designed to provide detailed information about userspace activity. Like the kernel tracer, performance is the main goal. Tracing does not require system calls or traps. UST instrumentation points may be added in any userspace code including signal handlers and libraries. . This package contains the UST library development files necessary to compile and link applications against liblttng-ust.
