NAME

       gd_entry_type — retrieve the type of a dirfile field

SYNOPSIS

       #include <getdata.h>

       gd_entype_t gd_entry_type(const DIRFILE *dirfile, const char *field_code);

DESCRIPTION

       The  gd_entry_type()  function  queries  a  dirfile(5)  database  specified by dirfile and
       returns the field type of the field specified by field_code.   If  field_code  contains  a
       valid representation suffix, it will be ignored.

       The gd_entype_t type is an enumerated type which may take any of the following values:

              GD_BIT_ENTRY, GD_CARRAY_ENTRY, GD_CONST_ENTRY, GD_DIVIDE_ENTRY, GD_INDEX_ENTRY,
              GD_LINCOM_ENTRY, GD_LINTERP_ENTRY, GD_MULTIPLY_ENTRY, GD_PHASE_ENTRY,
              GD_POLYNOM_ENTRY, GD_RAW_ENTRY, GD_RECIP_ENTRY, GD_SBIT_ENTRY, GD_STRING_ENTRY.

RETURN VALUE

       Upon successful completion, gd_entry_type() returns the field type of the specified field.
       On error, gd_entry_type() returns GD_NO_ENTRY and sets the dirfile error a non-zero  error
       value.  Possible error values are:

       GD_E_BAD_DIRFILE
               The supplied dirfile was invalid.

       GD_E_BAD_CODE
               The field specified by field_code was not found in the database.

       GD_E_BAD_REPR
               The representation suffix specified in field_code was not recognised.

       The dirfile error may be retrieved by calling gd_error(3).  A descriptive error string for
       the last error encountered can be obtained from a call to gd_error_string(3).
