cl_hp_parse_field - Execute field parser

       Michael Baeuerle

       The cl_hp_parse_field() function executes the header field parser.
       This implementation executes the canlock-hfp utility in a separate process.

       The parameter data should point to the beginning of the input data.
       Specify the length of the input data with the data_len parameter.

       The  input  data must be an unfolded "Cancel-Lock" or "Cancel-Key" header field without line break at the
       end.
       The function cl_hp_get_field() can be used to extract a field from the message header.
       The function cl_hp_unfold_field() can be used to remove  potential  folding  from  an  already  extracted
       header field.

       If  the  parser reports success, a pointer to the NUL-terminated output data is returned. Otherwise, NULL
       is returned.

       On success, the caller is responsible to free() the memory block allocated for the output data.
