gd_hidden — retrieve the fragment containing a dirfile field


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


The gd_hidden() function queries a dirfile(5) database specified by dirfile and indicates whether the field or alias called entry_name is hidden or not. This information is also available in the entry object proved by gd_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.).


Upon successful completion, gd_hidden() returns one if the field or alias is hidden, or zero if the entry is not hidden. On error it returns -1 and sets the dirfile error a non- zero error value. (As a result, the caller checking simply whether the return value of this function is non-zero is usually an error.) Possible error values are: 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. 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).
