ADSKeyCount()
Retrieve the number of keys in a specified index
---------------------------------------------------------------------------------
Syntax
ADSKeyCount([<xTag>], <cIgnoredIndexFile>, [<nFilterOption>]) -->
nKeyCount
Arguments
<xTag> Numeric order number OR index tag name. Default is
current index.
<cIgnoredIndexFile> This parameter is not processed. In
other Harbour RDDs, the second parameter to
"ordKeyCount" takes a second argument to identify a
particular Index File in cases where two files are open
that contain orders with the same name. The ADS driver
does not support this and will select the first order
with the requested name. To stay consistent with other
RDDs, therefore(),the second parameter is reserved and
the <nFilterOption> is passed as a third parameter.
<nFilterOption> Indicates if filters and/or scopes are to be
respected if set.
Options are defined in ads.ch:
+-------------------------------------------------+
| ADS_RESPECTFILTERS | Respect filters and scopes |
| ADS_IGNOREFILTERS | Ignore filters and scopes |
| ADS_RESPECTSCOPES | Respect scopes only |
+-------------------------------------------------+
Returns
<nKeyCount> The number of keys within the current index.
