#include <gnutls/gnutls.h>

int gnutls_pem_base64_decode(const char * header, const gnutls_datum_t * b64_data, unsigned char * result, size_t * result_size);

A null terminated string with the PEM header (eg. CERTIFICATE)
contain the encoded data
the place where decoded data will be copied

This function will decode the given encoded data. If the header given is non NULL this function will search for "-----BEGIN header" and decode only this part. Otherwise it will decode the first PEM packet found.
