@deftypefun {int} {gnutls_pkcs12_export} (gnutls_pkcs12_t @var{pkcs12}, gnutls_x509_crt_fmt_t @var{format}, void * @var{output_data}, size_t * @var{output_data_size})

@var{pkcs12}: A pkcs12 type

@var{format}: the format of output params. One of PEM or DER.

@var{output_data}: will contain a structure PEM or DER encoded

@var{output_data_size}: holds the size of output_data (and will be

replaced by the actual size of parameters)

This function will export the pkcs12 structure to DER or PEM format.

If the buffer provided is not long enough to hold the output, then

*output_data_size will be updated and GNUTLS_E_SHORT_MEMORY_BUFFER

will be returned.

If the structure is PEM encoded, it will have a header

of "BEGIN PKCS12".

@strong{Returns:} In case of failure a negative error code will be

returned, and 0 on success.
