Package: liblo0-dev
Version: 0.23-2.2
Severity: normal
When using the client and server code below, the parsing of a blob
argument is not correct. With liblo 0.26 it works as expected.
Client code:
int32_t testdata[] = {50000, 50001, 50002, 50003};
int main(int argc, char *argv[])
{
lo_blob btest = lo_blob_new(sizeof(int32_t)*4, testdata);
int i;
int32_t* data = lo_blob_dataptr(btest);
for (i=0; i<lo_blob_datasize(btest)/sizeof(int32_t); i++) {
printf("data[%d] = %i\n", i, data[i]);
}
lo_address t = lo_address_new(NULL, "7770");
lo_send(t, "/rwst", "b", btest);
lo_blob_free(btest);
return 0;
}
seems to build the blob correctly, according to the output:
Server Code:
int generic_handler(const char *path, const char *types, lo_arg **argv,
int argc, void *data, void *user_data)
{
int i;
for (i=0; i<argc; i++) {
if (types[i] == 'b') {
lo_blob b = argv[i];
int j;
int32_t *d = lo_blob_dataptr(b);
for (j=0; j<lo_blob_datasize(b)/sizeof(int32_t); j++) {
printf("d[%d]=%d\n", j, d[j]);
}
}
}
return 1;
}
int main()
{
lo_server_thread st = lo_server_thread_new("7770", NULL);
lo_server_thread_add_method(st, "/rwst", "b", generic_handler, NULL);
lo_server_thread_start(st);
while (1) usleep(1000);
return 0;
}
outputs:
d[0]=50001
d[1]=50002
d[2]=50003
d[3]=0
while the correct output should be:
d[0]=50000
d[1]=50001
d[2]=50002
d[3]=50003
lo_blob_datasize seems to be ok, i tried with different sizes, I also
tried with int32_t, chars and floats. The first value is always missing
the last is always 0.
As said before, with 0.26 it works.
cheers,
thomas
