gd_alter_protection

gd_alter_protection(3)						      GETDATA						    gd_alter_protection(3)

NAME

       gd_alter_protection -- modify the protection level of a dirfile fragment

SYNOPSIS

       #include <getdata.h>

       int gd_alter_protection(DIRFILE *dirfile, int protection_level, int fragment_index);

DESCRIPTION

       The  gd_alter_protection() function sets the advisory protection level of the format specification fragment given by fragment_index to pro-
       tection_level in the dirfile(5) database specified by dirfile.

       The protection_level argument should be one of the following:

       GD_PROTECT_NONE
	      Indicating that the fragment should not be protected at all.

       GD_PROTECT_FORMAT
	      Indicating that the fragment's metadata should be protected.

       GD_PROTECT_DATA
	      Indicating that the fragment's binary data should be protected.

       GD_PROTECT_ALL
	      Indicating that both the fragment's metadata and its binary data should be protected.  This symbol is equivalent to the  bitwise	or
	      of GD_PROTECT_FORMAT and GD_PROTECT_DATA.

       In addition to being simply a valid fragment index, fragment_index may also be the special value GD_ALL_FRAGMENTS, which indicates that the
       protection level of all fragments in the database should be changed.

RETURN VALUE

       Upon successful completion, gd_alter_protection() returns zero.	On error, it returns -1 and sets the dirfile error  to	a  non-zero  error
       value.  Possible error values are:

       GD_E_ACCMODE
	       The specified dirfile was opened read-only.

       GD_E_BAD_DIRFILE
	       The supplied dirfile was invalid.

       GD_E_BAD_INDEX
	       The supplied index was out of range.

       GD_E_BAD_PROTECTION
	       The supplied protection level 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).

NOTES

       This is the only GetData function which ignores the (existing) protection level of a format specification fragment.
