NAME
gd_encoding -- report the binary encoding of data in a dirfile SYNOPSIS
#include <getdata.h> unsigned long gd_encoding(DIRFILE *dirfile, int fragment_index); DESCRIPTION
The gd_encoding() function queries a dirfile(5) database specified by dirfile and returns the binary encoding for the fragment indexed by fragment_index. The binary encoding of a fragment indicate the encoding of data stored in binary files associated with RAW fields defined in the specified fragment. The encoding of a fragment containing no RAW fields is ignored. RETURN VALUE
Upon successful completion, gd_encoding() returns the binary encoding of the specified fragment, which will one of the following symbols: GD_UNENCODED, GD_TEXT_ENCODED, GD_SLIM_ENCODED, GD_GZIP_ENCODED, GD_BZIP2_ENCODED, GD_LZMA_ENCODED, GD_ENC_UNSUPPORTED. See gd_cbopen(3) and dirfile-encoding(5) for the meanings of these symbols and details on the supported encoding schemes. If the encoding scheme specified in the dirfile metadata is unknown to GetData, GD_ENC_UNSUPPORTED will be returned. On error, it returns zero and sets the dirfile error to a non-zero error value. Possible error values are: GD_E_BAD_DIRFILE The supplied dirfile was invalid. GD_E_BAD_INDEX The supplied index was out of range. 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). SEE ALSO

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. SEE ALSO
