gchar * tracker_sparql_get_uuid_urn (void
);
Generates a unique universal identifier to be used for urns when inserting SPARQL into the database. The string returned is in lower case and has the format "urn:uuid:%s" where %s is the uuid generated.
Returns : |
a newly-allocated string. The returned string should
be freed with g_free() when no longer needed. |
Since 0.10
gchar * tracker_sparql_escape_string (const gchar *literal
);
Escapes a string so that it can be used in a SPARQL query.
|
a string to escape |
Returns : |
a newly-allocated string with the escaped version of literal .
The returned string should be freed with g_free() when no longer needed. |
Since 0.10
gchar * tracker_sparql_escape_uri_printf (const gchar *format
,...
);
Calls tracker_sparql_escape_uri_vprintf()
with the @... supplied.
|
a standard printf() format string, but notice
string precision pitfalls documented in g_strdup_printf()
|
|
the parameters to insert into the format string |
Returns : |
a newly-allocated string holding the result.The returned string
should be freed with g_free() when no longer needed. |
Since 0.10
gchar * tracker_sparql_escape_uri_vprintf (const gchar *format
,va_list args
);
Similar to the standard C vsprintf()
function but safer, since it
calculates the maximum space required and allocates memory to hold
the result.
The result is escaped using g_uri_escape_string()
.

the list of parameters to insert into the format string |
Returns : |
a newly-allocated string holding the result. The returned string
should be freed with g_free() when no longer needed. |
