## Description

### Enum xlinkActuate

    Enum xlinkActuate {
        XLINK_ACTUATE_NONE = 0
        XLINK_ACTUATE_AUTO = 1
        XLINK_ACTUATE_ONREQUEST = 2
    }

### Structure xlinkHandler

    Structure xlinkHandler
    struct _xlinkHandler {
        xlinkSimpleLinkFunk	simple
        xlinkExtendedLinkFunk	extended
        xlinkExtendedLinkSetFunk	set
    }

### Enum xlinkShow

    Enum xlinkShow {
        XLINK_SHOW_NONE = 0
        XLINK_SHOW_NEW = 1
        XLINK_SHOW_EMBED = 2
        XLINK_SHOW_REPLACE = 3
    }

### Enum xlinkType

    Enum xlinkType {
        XLINK_TYPE_NONE = 0
        XLINK_TYPE_SIMPLE = 1
        XLINK_TYPE_EXTENDED = 2
        XLINK_TYPE_EXTENDED_SET = 3
    }

### Function type: xlinkExtendedLinkFunk

    Function type: xlinkExtendedLinkFunk
    void	xlinkExtendedLinkFunk		(void * ctx,
    					 xmlNodePtr node,
    					 int nbLocators,
    					 const xlinkHRef * hrefs,
    					 const xlinkRole * roles,
    					 int nbArcs,
    					 const xlinkRole * from,
    					 const xlinkRole * to,
    					 xlinkShow * show,
    					 xlinkActuate * actuate,
    					 int nbTitles,
    					 const xlinkTitle * titles,
    					 const xmlChar ** langs)

This is the prototype for a extended link detection callback.

`ctx`: | user data pointer
`node`: | the node carrying the link
`nbLocators`: | the number of locators detected on the link
`hrefs`: | pointer to the array of locator hrefs
`roles`: | pointer to the array of locator roles
`nbArcs`: | the number of arcs detected on the link
`from`: | pointer to the array of source roles found on the arcs
`to`: | pointer to the array of target roles found on the arcs
`show`: | array of values for the show attributes found on the arcs
`actuate`: | array of values for the actuate attributes found on the arcs
`nbTitles`: | the number of titles detected on the link
`titles`: |
`langs`: | array of xml:lang values for the titles

### Function type: xlinkExtendedLinkSetFunk

    Function type: xlinkExtendedLinkSetFunk
    void	xlinkExtendedLinkSetFunk	(void * ctx,
    					 xmlNodePtr node,
    					 int nbLocators,
    					 const xlinkHRef * hrefs,
    					 const xlinkRole * roles,
    					 int nbTitles,
    					 const xlinkTitle * titles,
    					 const xmlChar ** langs)

This is the prototype for a extended link set detection callback.

`ctx`: | user data pointer
`node`: | the node carrying the link
`nbLocators`: | the number of locators detected on the link
`hrefs`: | pointer to the array of locator hrefs
`roles`: | pointer to the array of locator roles
`nbTitles`: | the number of titles detected on the link
`titles`: |
`langs`: | array of xml:lang values for the titles

### Function: xlinkGetDefaultDetect

    xlinkNodeDetectFunc	xlinkGetDefaultDetect	(void)

Get the default xlink detection routine

`Returns`: | the current function or NULL;

### Function: xlinkGetDefaultHandler

    xlinkHandlerPtr	xlinkGetDefaultHandler	(void)

Get the default xlink handler.

`Returns`: | the current xlinkHandlerPtr value.

### Function: xlinkIsLink

    xlinkType	xlinkIsLink		(xmlDocPtr doc,
    					 xmlNodePtr node)

Check whether the given node carries the attributes needed to be a link element (or is one of the linking elements issued from the (X)HTML DtDs). This routine don't try to do full checking of the link validity but tries to detect and return the appropriate link type.

`doc`: | the document containing the node
`node`: | the node pointer itself
`Returns`: | the xlinkType of the node (XLINK_TYPE_NONE if there is no link detected.

### Function type: xlinkNodeDetectFunc

    Function type: xlinkNodeDetectFunc
    void	xlinkNodeDetectFunc		(void * ctx,
    					 xmlNodePtr node)

This is the prototype for the link detection routine. It calls the default link detection callbacks upon link detection.

`ctx`: | user data pointer
`node`: | the node to check

### Function: xlinkSetDefaultDetect

    void	xlinkSetDefaultDetect		(xlinkNodeDetectFunc func)

Set the default xlink detection routine

`func`: | pointer to the new detection routine.

### Function: xlinkSetDefaultHandler

    void	xlinkSetDefaultHandler		(xlinkHandlerPtr handler)

Set the default xlink handlers

`handler`: | the new value for the xlink handler block

### Function type: xlinkSimpleLinkFunk

    Function type: xlinkSimpleLinkFunk
    void	xlinkSimpleLinkFunk		(void * ctx,
    					 xmlNodePtr node,
    					 const xlinkHRef href,
    					 const xlinkRole role,
    					 const xlinkTitle title)

This is the prototype for a simple link detection callback.

`ctx`: | user data pointer
`node`: | the node carrying the link
`href`: | the target of the link
`role`: | the role string
`title`: | the link title
