]> Prefixes 3 RASQAL Library Prefixes XML QName-style prefixes made from a URI and a short text prefix. rasqal_prefix; rasqal_prefix* rasqal_new_prefix (unsigned char *prefix, raptor_uri *uri); void rasqal_free_prefix (rasqal_prefix *p); void rasqal_prefix_print (rasqal_prefix *p, FILE *fh); Used inside a rasqal_query to declare syntax prefix abbreviations for URIs. Once a rasqal_query is constructed, these are for information only. rasqal_prefixtypedef struct { const unsigned char *prefix; raptor_uri* uri; int declared; int depth; } rasqal_prefix; Namespace (prefix, uri) pair. Includes internal flags used for marking when prefixes are declared and at what XML element depth when used in XML formats. raptor_uri *uri; URI associated with the prefix. int declared; Internal flag. int depth; Internal flag. rasqal_new_prefixrasqal_prefix* rasqal_new_prefix (unsigned char *prefix, raptor_uri *uri); Constructor - create a new rasqal_prefix. Takes ownership of prefix and uri. prefix : Short prefix string to stand for URI or NULL. uri : Name raptor_uri. Returns : a new rasqal_prefix or NULL on failure. rasqal_free_prefixvoid rasqal_free_prefix (rasqal_prefix *p); Destructor - destroy a rasqal_prefix object. p : rasqal_prefix object. rasqal_prefix_printvoid rasqal_prefix_print (rasqal_prefix *p, FILE *fh); Print a Rasqal prefix in a debug format. The print debug format may change in any release. p : rasqal_prefix object. fh : The FILE* handle to print to.
