GSF_ERROR#define GSF_ERROR (gsf_error_quark ())
This convenience macro simply calls gsf_error_quark(). You can use
it in calls to g_error_matches(), for example. The macro returns
the GQuark that is used to identify errors from libgsf functions.
Specific error codes come from the GsfError enumeration.
<anchor id="GsfError"/>enum GsfError
GsfErrortypedef enum {
GSF_ERROR_OUT_OF_MEMORY,

} GsfError;
Error codes that can be returned from libgsf functions in GError structures.
GSF_ERROR_OUT_OF_MEMORY
Not enough memory could be allocated to hold
a structure or object.
GSF_ERROR_INVALID_DATA
A file being read contained invalid or
inconsistent data.
<anchor id="gsf-error-quark"/>gsf_error_quark ()
gsf_error_quarkGQuark gsf_error_quark (void);
Returns the GQuark used to identify libgsf errors in GError structures.
Specific error codes come from the GsfError enumeration.
Returns : A GQuark.
<anchor id="gsf-mem-dump"/>gsf_mem_dump ()

<anchor id="gsf-input-dump"/>gsf_input_dump ()
gsf_input_dumpvoid gsf_input_dump (GsfInput *input,

a GsfInput
dump_as_hex :
If TRUE, dump in hexidecmal format

A utility wrapper to make sure filenames are valid utf8.
Caller must g_free the result.
filename :
file name suitable for open(2).
quoted :
if TRUE, the resulting utf8 file name will be quoted
(unless it is invalid).

A filename or file path.
Returns : A pointer to the extension part of the filename, or a
pointer to the end of the string if the filename does not
have an extension.

This function builds a GParameter array suitable for g_object_newv.
object_type :
the GType for which the properties are being set.
p_params :
a pointer to the GParameter array that holds the properties.
(Used for both input and output. This may point to a NULL pointer if
there are no properties collected yet.)
p_n_params :
a pointer to the number of properties collected. (Used for
both input and output.)
first_property_name :
the name of the first property being set, or NULL.
var_args :
a va_list holding the remainder of the property names and
values, terminated by a NULL.
