.SH DESCRIPTION
.SS Purpose
Use \s-2INQUIRE STRUCTURE STATUS\s+2 to determine the existence status
of the specified structure (\s-2NON_EXISTENT\s+2, \s-2EMPTY\s+2,
or \s-2NOTEMPTY\s+2).
.SS C Input Parameters
.IP \fIstruct_id\fP
Identifier of the structure for which the status is to be returned.
.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 \fIstruct\fP
A pointer to a Pstruct_status enumerated variable in which the system returns the existence status of the specified structure.
Values for Pstruct_status are defined in phigs.h as follows:
.nf
.ta .5i
.sp
	PSTRUCT_STATUS_NON_EXISTENT
	PSTRUCT_STATUS_EMPTY
	PSTRUCT_STATUS_NOT_EMPTY
