Constructor - make a new XSD date object from a string

world :

 world object

date_string :

 XSD date string

Returns :

 new datetime or NULL on failure

rasqal_free_xsd_date ()

void                rasqal_free_xsd_date                (rasqal_xsd_date *d);

Destroy XSD date object.

Convert a rasqal_xsd_date struct to a xsd:date lexical form string.

Caller should rasqal_free_memory() the returned string.

See http://www.w3.org/TR/xmlschema-2/date-canonical-representation

date :

 date struct

len_p :

 output length (or NULL)

Returns :

 lexical form string or NULL on failure.

rasqal_xsd_date_to_string ()

char *              rasqal_xsd_date_to_string           (const rasqal_xsd_date *d);

Convert a rasqal_xsd_date struct to a xsd:date lexical form string.

Caller should rasqal_free_memory() the returned string.

d :

 date struct

Returns :

 lexical form string or NULL on failure.

rasqal_xsd_date_equals ()

int                 rasqal_xsd_date_equals              (const rasqal_xsd_date *d1,
                                                         const rasqal_xsd_date *d2,

Compare two XSD dates for equality.

d1 :

 first XSD date

d2 :

 second XSD date

incomparible_p :

 address to store incomparable flag (or NULL)

Returns :

 non-0 if equal.

rasqal_xsd_date_compare ()

int                 rasqal_xsd_date_compare             (const rasqal_xsd_date *d1,
                                                         const rasqal_xsd_date *d2,

Compare two XSD dates

If the only one of the two dates have timezones, the results may be incomparible and that will return >0 and set the value of the int point to by incomparible_p to non-0

d1 :

 first XSD date

d2 :

 second XSD date

incomparible_p :

 address to store incomparable flag (or NULL)

Returns :

 <0 if d1 is less than d2, 0 if equal, >0 otherwise
