Function opensc_sys::list_attributes_unserializer

    l: *mut list_t, 
    unserializer_fun: element_unserializer
) -> c_int

set the element unserializer function for the list elements.

[ advanced preference ]

Unserialize functions are used for restoring the list from some persistent storage. The unserializer function is called for each element segment read from the storage; it is passed the segment and a reference to an integer. It shall allocate and return a buffer compiled with the resumed memory representation of the element, and set the integer value to the length of this buffer.

@param l list to operate @param unserializer_fun pointer to the actual unserializer function @return 0 if the attribute was successfully set; -1 otherwise
