N_CHECKF( [ <nStanum> ] )


Parameters

<nStanum>
Optional station number to query. If omitted, all currently logged-in 
stations, except for the current station, are queried.


Returns

A one byte string containing the ASCII code of the station number (CHR 
1-255), if any, that has the current file locked with FLOCK(). The 
number of the current station is never returned, even if it does have 
the file locked.  Use N_ISFLOCK() to detect if the current station has 
the file locked.

This is different than in earlier versions of NetLib for Clipper, which 
would return the station that had the current file locked, or the list 
of stations that had an RLOCK() in the current file.


Description

If <nStanum> is specified, then only that station is queried.
