Ok. I've compiled libzip.
I can read entries names but how can I pass buffer to Javascript for this C
function?
int zipG(const char* zip_file_name, char* ZipBuf2) {
int v1=zip_entry_opencasesensitive(gloablZip, zip_file_name);
cout << v1 << endl;
zip_entry_read(gloablZip, (void**)&ZipBuf2, &ZipBuf_size);
cout << ZipBuf_size << endl;
return 0;
}
in JS:
var myBuffer= cArray8(32000)
Module.ccall('zipG', 'number', ['string','number'],
['model.dat',myBuffer.offset]);
function cArray8(size) {
var offset = Module._malloc(size * 1);
Module.HEAP8.set(new Uint8Array(size), offset / 1);
return {
"data": Module.HEAP8.subarray(offset / 1, offset / 1 + size),
"offset": offset
}
};
