) -> c_int

Get the IO handle’s contents. If the handle doesn’t use an in-memory buffer, this function returns #GNUNET_SYSERR.

@param h the IO handle @param emsg set to the (allocated) error message if the handle has an error message the return value is #GNUNET_SYSERR @param contents where to store the pointer to the handle’s contents @param size where to store the size of @e contents @return #GNUNET_OK on success, #GNUNET_SYSERR otherwise
