* If in buffer descriptor mode a pointer to gcry_buffer_t descriptor
* is expected instead of a pointer to an MPI. The caller may use two
* different operation modes: If the DATA field of the provided buffer
* descriptor is NULL, the function allocates a new buffer and stores
* it at DATA; the other fields are set accordingly with OFF being 0.
* If DATA is not NULL, the function assumes that DATA, SIZE, and OFF
* describe a buffer where to but the data; on return the LEN field
* receives the number of bytes copied to that buffer; if the buffer
* is too small, the function immediately returns with an error code
* (and LEN set to 0).
*
* PATH is an optional string used to locate a token. The exclamation
* mark separated tokens are used to via gcry_sexp_find_token to find
* a start point inside SEXP.
*
* The function returns 0 on success. On error an error code is
* returned, all passed MPIs that might have been allocated up to this
* point are deallocated and set to NULL, and all passed buffers are
* either truncated if the caller supplied the buffer, or deallocated
* if the function allocated the buffer.
