DESCRIPTION

Purpose

Use INQUIRE WORKSTATION CATEGORY to determine the category of a specified workstation type. 

C Input Parameters

type
Type of workstation.

C Output Parameters

error_ind
A pointer to the location to store the error number of any error detected by this function.

category
A pointer to a Pws_cat enumerated variable, in which the workstation category is returned. Values for Pws_cat are defined in phigs.h as follows:

typedef enum {
PCAT_OUT,/∗ Output Only ∗/
PCAT_IN,/∗ Input Only ∗/
PCAT_OUTIN,/∗ Output and Input ∗/
PCAT_MO,/∗ Metafile Output ∗/
PCAT_MI/∗ Metafile Input ∗/
} Pws_cat;

Execution

If the inquired information is available, the error indicator is returned as zero and values are returned in the output parameters. 

If the inquired information is not available, the values returned in the output parameters are undefined and the error indicator is set to one of the below error numbers to indicate the reason for nonavailability. 

Since this is an inquiry function, ERROR HANDLING is not invoked when an error is detected by this function. 

ERRORS

002Ignoring function, function requires state (PHOP, ∗, ∗, ∗)

052Ignoring function, workstation type not recognized by the implementation

051Ignoring function, this information is not yet available for this workstation type; open a workstation of this type and use the specific workstation type
