3 @deftypefun {const char *} {asn1_check_version} (const char * @var{req_version})
4 @var{req_version}: Required version number, or @code{NULL}.
6 Check that the version of the library is at minimum the
7 requested one and return the version string; return @code{NULL} if the
8 condition is not satisfied. If a @code{NULL} is passed to this function,
9 no check is done, but the version string is simply returned.
11 See @code{ASN1_VERSION} for a suitable @code{req_version} string.
13 @strong{Returns:} Version string of run-time library, or @code{NULL} if the
14 run-time library does not meet the required version number.
