get_entry_type

NAME

get_entry_type --- retrieve the type of a dirfile field

SYNOPSIS

#include <getdata.h>

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

DESCRIPTION

The get_entry_type() function queries a dirfile(5) database specified by dirfile and returns the field type of the field specified by field_code.

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

GD_BIT_ENTRY,~GD_CONST_ENTRY,~GD_INDEX_ENTRY,~ GD_LINCOM_ENTRY,~GD_LINTERP_ENTRY,~GD_MULTIPLY_ENTRY,~ GD_PHASE_ENTRY,~GD_RAW_ENTRY,~GD_STRING_ENTRY.

RETURN VALUE

Upon successful completion, get_entry_type() returns the field type of the specified field. On error, get_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.

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