.SH DESCRIPTION
.SS Purpose
Use \s-2INQUIRE WORKSTATION TRANSFORMATION\s+2 to determine the current
and requested \s-2\&2D\s+2 workstation transformation
from a specified workstation's state list.
.SS C Input Parameter
.IP \fIws\fP
The \fIworkstation identifier\fP of the workstation whose state list is queried.
.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 \fIupd_st\fP
The current update state. Pupd_st is defined in phigs.h as follows:
.sp .4
.nf
typedef enum {
.sp .2
.ta .5i
PUPD_NOT_PEND
PUPD_PEND
.sp .2
} Pupd_st;
.fi
.IP \fIreq_win_lim\fP
The requested workstation window. Plimit is defined in phigs.h as follows:
.sp .4
.nf
.ta .5i +\w'Pfloat 'u +\w'x_min; 'u
typedef struct {
.sp .2
Pfloat x_min;
Pfloat x_max;
Pfloat y_min;
Pfloat y_max;
.sp .2
} Plimit;
.fi
.IP \fIcur_win_lim\fP
The current workstation window. Plimit is defined above.
.IP \fIreq_vp_lim\fP
The requested workstation viewport. Plimit is defined above.
.IP \fIcur_vp_lim\fP
The current workstation viewport. Plimit is defined above.
.SS Execution
The requested and current entries may differ if a workstation transformation
change has been requested, but has not yet been provided. The update
state will be \fIPending\fP in this case, and \fINot Pending\fP otherwise.
.SH ERRORS
.IP 003
Ignoring function, function requires state
(\s-2PHOP\s+2, \s-2WSOP\s+2, \s-2*\s+2, \s-2*\s+2)
.IP 054
Ignoring function, the specified workstation is not open
.IP 057
Ignoring function, specified workstation is of category \s-2MI\s+2
