Prototype for the plugin validation function
#include <mm/mmplaylist.h>
typedef int mmplaylist_pl_validation_fn_t(char *raw, char *encoded, void *cbk_data);
The mmplaylist_pl_validation_fn_t data type specifies the prototype for a function that validates plugin names. This optional function can be defined to override a plugin's default validation function. It will try to validate which entry name is correct: the raw name or the UTF-8 one. See the mmplaylist_entry_next_get() description for an explanation of playlist entry validation.
An MMPLAYLIST_PL_ENTRY_* constant indicating the outcome of the validation or that the validation attempt failed.
