Packit 423ecb 
      A handle to a dynamically loaded module
Packit 423ecb 
    
Function: xmlModuleClose
int	xmlModuleClose			(xmlModulePtr module)
Packit 423ecb 
The close operations unload the associated module and free the data associated to the module.
Packit 423ecb 
<tt>module</tt>:the module handle
<tt>Returns</tt>:0 in case of success, -1 in case of argument error and -2 if the module could not be closed/unloaded.
Function: xmlModuleFree
int	xmlModuleFree			(xmlModulePtr module)
Packit 423ecb 
The free operations free the data associated to the module but does not unload the associated shared library which may still be in use.
Packit 423ecb 
<tt>module</tt>:the module handle
<tt>Returns</tt>:0 in case of success, -1 in case of argument error
Function: xmlModuleOpen
xmlModulePtr	xmlModuleOpen		(const char * name, 
					 int options)
Packit 423ecb 
Opens a module/shared library given its name or path NOTE: that due to portability issues, behaviour can only be guaranteed with @name using ASCII. We canot guarantee that an UTF-8 string would work, which is why name is a const char * and not a const xmlChar * . TODO: options are not yet implemented.
Packit 423ecb 
<tt>name</tt>:the module name
<tt>options</tt>:a set of xmlModuleOption
<tt>Returns</tt>:a handle for the module or NULL in case of error
Function: xmlModuleSymbol
int	xmlModuleSymbol			(xmlModulePtr module, 
					 const char * name, 
					 void ** symbol)
Packit 423ecb 
Lookup for a symbol address in the given module NOTE: that due to portability issues, behaviour can only be guaranteed with @name using ASCII. We canot guarantee that an UTF-8 string would work, which is why name is a const char * and not a const xmlChar * .
Packit 423ecb 
<tt>module</tt>:the module
<tt>name</tt>:the name of the symbol
<tt>symbol</tt>:the resulting symbol address
<tt>Returns</tt>:0 if the symbol was found, or -1 in case of error
