void *(* get_interface )(const XQC_DynamicContext *context, const char *name)
 Called to retrieve an implementation specific interface.
void(* free )(XQC_DynamicContext *context)
 Called to free the resources associated with the XQC_DynamicContext.

Detailed Description

Examples:

xqc-context-item.c.


Member Data Documentation

Called to free the resources associated with the XQC_DynamicContext.

Parameters:
context The XQC_DynamicContext that this function pointer is a member of
Examples:
xqc-context-item.c.
void*(* XQC_DynamicContext_s::get_interface)(const XQC_DynamicContext *context, const char *name)

Called to retrieve an implementation specific interface.

Parameters:
context The XQC_DynamicContext that this function pointer is a member of
name The name that identifies the interface to return
Returns:
A pointer to the interface, or 0 if the name is not recognized by this implementation of XQC.
XQC_Error(* XQC_DynamicContext_s::get_variable)(const XQC_DynamicContext *context, const char *uri, const char *name, XQC_Sequence **value)

Sets the context item to the current item of the XQC_Sequence given.

The user remains responsible for freeing the XQC_Sequence passed as the value - the XQC_Sequence must not be freed until the XQC_DynamicContext has been freed or it's context item set to a different value.

Parameters:
context The XQC_DynamicContext that this function pointer is a member of
value The XQC_Sequence value for the context item, or 0 to remove the existing context item value.
Return values:
XQC_NO_ERROR 
XQC_INTERNAL_ERROR 
XQC_NO_CURRENT_ITEM if there is no current item in the value.
Examples:
xqc-context-item.c.

The timezone given must be between -840 and +840 minutes (-14 and +14 hours).

Parameters:
timezone The implicit timezone to set, as an offset in minutes from GMT
XQC_Error(* XQC_DynamicContext_s::set_variable)(XQC_DynamicContext *context, const char *uri, const char *name, XQC_Sequence *value)

Sets the external variable to the value given.

The implementation takes ownership of the XQC_Sequence passed in, and is responsible for freeing it.

Parameters:
context The XQC_DynamicContext that this function pointer is a member of
uri The namespace URI of the external variable to set.
name The name of the external variable to set - this should be a valid lexical xs:QName. If uri is 0 and name has a prefix, that prefix is resolved using the in-scope namespace prefixes for the expression.
value The XQC_Sequence value for the variable, or 0 to remove the existing binding for the variable.
Return values:
XQC_NO_ERROR 
XQC_INTERNAL_ERROR
