.ARG field_code
contains a valid representation suffix, it will be ignored.

The
.B gd_entype_t
type is an enumerated type which may take any of the following values:
.IP
.SC
.BR GD_BIT_ENTRY ,
.BR GD_CARRAY_ENTRY ,
.BR GD_CONST_ENTRY ,
.BR GD_DIVIDE_ENTRY ,
.BR GD_INDEX_ENTRY ,
.BR GD_INDIR_ENTRY ,
.BR GD_LINCOM_ENTRY ,
.BR GD_LINTERP_ENTRY ,
.BR GD_MPLEX_ENTRY ,
.BR GD_MULTIPLY_ENTRY ,
.BR GD_PHASE_ENTRY ,
.BR GD_POLYNOM_ENTRY ,

.BR GD_STRING_ENTRY ,
.BR GD_WINDOW_ENTRY .
.EC

.SH RETURN VALUE
Upon successful completion,
.FN gd_entry_type
returns the field type of the specified field.  On error,
.FN gd_entry_type
returns
.B GD_NO_ENTRY
and stores a negative-valued error code in the
.B DIRFILE
object which may be retrieved by a subsequent call to
.F3 gd_error .
Possible error codes are:
.DD GD_E_BAD_DIRFILE
The supplied dirfile was invalid.
.DD GD_E_BAD_CODE
The field specified by
.ARG field_code
was not found in the database.
.PP
A descriptive error string for the error may be obtained by calling
.F3 gd_error_string .
