.SH DESCRIPTION
.SS Purpose
Use \s-2INQUIRE NUMBER OF DISPLAY PRIORITIES SUPPORTED\s+2 to determine
the number of display priorities supported by a specified workstation type.
.LP
If the number of priorities returned is zero, this means the workstation type
can support an arbitrary number of priorities.
.SS C Input Parameters
.IP \fIwst\fP
Workstation type.
.SS C Output Parameters
.IP \fIerror_ind\fP
A pointer to the location to store the error number of any error
detected by this function.
.IP \fInum_pri\fP
A pointer to an integer that stores the number of display priorities supported
on workstations of type \fIwst\fP.
.SH ERRORS
.IP 002
Ignoring function, function requires state (\s-2PHOP, *, *, *\s+2)
.IP 051
Ignoring function, this information is not yet available
for this workstation type; open a workstation of this type
and use the specific workstation type
.IP 052
Ignoring function, workstation type not recognized by the implementation
.IP 059
Ignoring function, the specified workstation does not have
output capability (that is, the workstation category is neither
\s-2OUTPUT\s+2, \s-2OUTIN\s+2, nor \s-2MO\s+2)
.IP 062
Ignoring function, this information is not available for this
\s-2MO\s+2 workstation type
