asn1_check_version(3) API function


#include <libtasn1.h>

const char * asn1_check_version(const char * req_version);


const char * req_version
Required version number, or NULL.


Check that the version of the library is at minimum the requested one and return the version string; return NULL if the condition is not satisfied. If a NULL is passed to this function, no check is done, but the version string is simply returned.

See ASN1_VERSION for a suitable req_version string.


Version string of run-time library, or NULL if the run-time library does not meet the required version number.
