gd_hideSYNOPSIS
#include <getdata.h>-
int gd_hide(const DIRFILE *dirfile, const char
*entry_name);
- int gd_unhide(const DIRFILE *dirfile, const char *entry_name);
DESCRIPTION
A hidden entry does not appear in the field lists returned by the functions gd_field_list(3), gd_field_list_by_type(3), gd_vectors(3), gd_constants(3), and gd_strings(3). These omissions are also reflected in the counts returned by the corresponding field counting functions (gd_nfields(3), &c.). A hidden field is otherwise no different than an unhidden field.
RETURN VALUE
Upon successful completion, gd_hide() and gd_unhide() return zero. On error they returns -1 and sets the dirfile error a non-zero error value. Possible error values are:- GD_E_ACCMODE
- The specified dirfile was opened read-only.
- GD_E_BAD_CODE
- The field specified by field_code was not found in the database.
- GD_E_BAD_DIRFILE
- The supplied dirfile was invalid.
- GD_E_PROTECTED
- The metadata of the affected format specification fragments was protected from change.
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).
