NAME
gffdMatchName, gffdMatchData - perform matching operations
SYNOPSIS
#include <gffd/gffd.h>
int gffdMatchName(gffd_context_t ctx, const char *name);
int gffdMatchData(gffd_context_t ctx, const unsigned char *data,
int length);
DESCRIPTION
Matches are operations which update the score values of the set of
possible matches stored in the matching context. The set of matches
is kept in sorted order, from highest score to lowest score, so that
the best match will always be at index #0. Match operations do not
remove possible matches from the set.
gffdMatchName() matches the given filename against the current
set of possible matches, using the name information contained in the
LibGFFD file format database.
gffdMatchData() matches the file's data (taken from the
beginning of the file) against the current set of possible matches,
using the magic-number information contained in the LibGFFD file
format database.
For the best matching results, it is recommended that both
gffdMatchName() and gffdMatchData() are called. This is not
compulsory however, LibGFFD can be used to match based solely on
filenames or solely on magic numbers.
RETURN VALUES
On success, gffdMatchName() and gffdMatchData() return zero, otherwise
they return a negative error code.
