sub taglib_set_strings_unicode

sub taglib_set_strings_unicode(
    int32 $unicode
) returns Mu

By default all strings coming into or out of TagLib's C API are in UTF8. However, it may be desirable for TagLib to operate on Latin1 (ISO-8859-1) strings in which case this should be set to FALSE.

sub taglib_set_string_management_enabled

sub taglib_set_string_management_enabled(
    int32 $management
) returns Mu

TagLib can keep track of strings that are created when outputting tag values and clear them using taglib_tag_clear_strings(). This is enabled by default. However if you wish to do more fine grained management of strings, you can do so by setting \a management to FALSE.

    NativeCall::Types::Pointer $pointer
) returns Mu

Explicitly free a string returned from TagLib

sub taglib_file_new

sub taglib_file_new(
    Str $filename

Creates a TagLib file based on \a filename. TagLib will try to guess the file type. \returns NULL if the file type cannot be determined or the file cannot be opened.

sub taglib_file_new_type

sub taglib_file_new_type(
    Str $filename, 
    int32 $type
) returns TagLibC::File

Creates a TagLib file based on \a filename. Rather than attempting to guess the type, it will use the one specified by \a type.

    TagLibC::File $file
) returns Mu

Frees and closes the file.

sub taglib_file_tag
