asn1_find_node

Function: asn1_node asn1_find_node (asn1_node pointer, const char * name)

pointer: NODE_ASN element pointer.

name: null terminated string with the element’s name to find.

Searches for an element called name starting from pointer. The name is composed by differents identifiers separated by dots. When *pointer has a name, the first identifier must be the name of *pointer, otherwise it must be the name of one child of *pointer.

Returns: the search result, or NULL if not found.

asn1_check_version

Function: const char * asn1_check_version (const char * req_version)

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.

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