List of all tags. 0x0000  0

The special tag 0 (Zero) allows an application to determine all of the tags that a particular driver supports.

Type:

IG_ISIS_TAG_TYPE_LONG

Drivers:

All.

Values:

The 0 tag contains a list of all the tags as numeric values. Use IG_ISIS_tag_get_length to get the number of tags, and then use IG_ISIS_tag_get_long with an index value to get the list of tags.

Example:

 
Copy Code
HISISDRV hDriver;  //Set to valid ISIS driver handle.
DWORD uNumTags, uTag;
INT32 lValue;
//Determine number of tags in driver.IG_ISIS_tag_get_length(hDriver, 0, &uNumTags);
//Cycle through tags in driver.
for (uTag = 0; uTag < uNumTags; uTag++)
{
    //Find out tag number at index position.IG_ISIS_tag_get_long(hDriver, 0, uTag, &lValue);
    //Do something with lValue.
}
