The benefit is better performance, compared to the other service deployment methods. Stand-alone service deployment in uncontrolled high-risk environments is not recommended and you assume all risks which means you should carefully weigh the risks of this scenario. To stay safe, periodically check our [advisories] advisory. The main program of a stand-alone multi-threaded service calls bind and listen to a port, accept, and spawns a new thread for each request: [codetab.

Memory management is automatic in gSOAP to avoid leaks. The above example uses a very simple example schema. The gSOAP toolkit also handles multiple schemas defined in multiple namespaces. For example, if we would combine two schemas in the same application where both schemas define a book object, we need to resolve this conflict. This requires a "stub function", also called "service proxy", for each service operation that the client invokes.
With the stub function in place, the client application invokes a remote service operation as if it would invoke a local function. The soapcpp2 tool generates the necessary gluing code the client stub functions and server skeleton functions to build web service clients and services. The following command: wsdl2h -o calc. To generate C code, we use wsdl2h -c option -c : wsdl2h -c -o calc. When upgrading gSOAP to a newer version it is often not necessary to perform this first step again, since newer versions are backward compatible to previous interface header files generated by wsdl2h.
Looking into the file calc. The convention to add an XML namespace prefix to the names of operations, types, and struct and class members is universally used by the gSOAP tools and automatically added by wsdl2h. Next, the calc. The input and output parameters of a service operation may be primitive data types or compound data types, such as containers and pointer-based linked data structures.
These are defined in the interface header file, which is either generated by the wsdl2h tool or it may be specified by hand. The soapcpp2 tool automatically generates XML serializers and XML deserializers for these data types to enable the generated stub functions to serialize the contents of the parameters of the service operations in XML.
The soapcpp2 tool also generates "skeleton functions" soapServer. The skeleton functions can be readily used to implement one or more of the service operations in a new XML Web service. See the following section. The calc.
