Synopsis
--------

*#include <ngtcp2/ngtcp2.h>*

.. function:: const ngtcp2_info *ngtcp2_version(int least_version)

    
    `ngtcp2_version` returns a pointer to a :type:`ngtcp2_info` struct
    with version information about the run-time library in use.  The
    *least_version* argument can be set to a 24 bit numerical value for
    the least accepted version number, and if the condition is not met,
    this function will return a ``NULL``.  Pass in 0 to skip the
    version checking.
