gd_hide, gd_unhide — hide or unhide a dirfile database entry


#include <getdata.h> int gd_hide(const DIRFILE *dirfile, const char *entry_name); int gd_unhide(const DIRFILE *dirfile, const char *entry_name);


The gd_hide() function hides the field or alias called entry_name in the dirfile(5) data‐ base specified by dirfile and indicates whether the field or alias called is hidden or not. Similarly, the gd_unhide() function unhides the specified entry. An entry can also be hidden or unhidden using gd_alter_entry(3). 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 corre‐ sponding field counting functions (gd_nfields(3), &c.). A hidden field is otherwise no different than an unhidden field.


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).
