gd_entry_type(3) GETDATA gd_entry_type(3)NAMEgd_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_MPLEX_ENTRY, GD_MULTIPLY_ENTRY, GD_PHASE_ENTRY,
GD_POLYNOM_ENTRY, GD_RAW_ENTRY, GD_RECIP_ENTRY, GD_SBIT_ENTRY,
GD_STRING_ENTRY, GD_WINDOW_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_ALLOC
The library was unable to allocate memory.
GD_E_BAD_DIRFILE
The supplied dirfile was invalid.
GD_E_BAD_CODE
The field specified by field_code was not found in the data‐
base.
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 descrip‐
tive error string for the last error encountered can be obtained from a
call to gd_error_string(3).
