Hi,
I'm working on ext/id3 (proposed in pecl) and I'm currently experiencing a problem.
I got a function that is used to update the information in an ID3 tag. The user passes an array and I update all information that has been passed. One of the possible tokens is a genre ID which is represented by an integer:
$new = array(
'title' => 'My Song',
'genre' => 23
);Now I need to write the character that represents 34 to the stream. Using
zend_hash_get_current_data(array, (void**) &data);
I copy the value 23 into data. Then I convert it to long, if the value is not a long already:
convert_to_long(*data);
And now I move the pointer to the position where the genre ID is stored:
php_stream_seek(stream, ID3_SEEK_V1_GENRE, SEEK_END);
But I do not know how to write the value to the stream
php_stream_write(stream, (char*)Z_LVAL_P(*data), 1);
This does not produce the result I need, instead the file contains 48 at this position.
If I return RETURN_LONG(Z_LVAL_P(*data); I get 23 as expected.
Hope anybody is able to help or direct me to the correct mailinglist if internals is not the appropriate list.
Best regards,
Stephan
