which is a 24 bit number in the 0xMMmmpp format. MM for major, mm for
minor and pp for patch number.

RETURN VALUE

The version number of libssh2 is returned as a pointer to a zero
terminated string or NULL if the required_version is not fulfilled.

EXAMPLE

To make sure you run with the correct libssh2 version:

if(!libssh2_version(LIBSSH2_VERSION_NUM)) {
fprintf(stderr, "Runtime libssh2 version too old!");
exit(1);
}

Unconditionally get the version number:

printf("libssh2 version: %s", libssh2_version(0));

AVAILABILITY

way no way to extract this info in run-time.
