char * soup_xmlrpc_build_method_call (const char *method_name,GValue *params,int n_params);
This creates an XML-RPC methodCall and returns it as a string.
This is the low-level method that soup_xmlrpc_request_new() is
built on.
params is an array of GValue representing the parameters to
method. (It is *not* a GValueArray, although if you have a
GValueArray, you can just pass its valuesf and
n_values fields.)
The correspondence between glib types and XML-RPC types is:
  int: int (G_TYPE_INT)
  boolean: gboolean (G_TYPE_BOOLEAN)
  string: char* (G_TYPE_STRING)
  double: double (G_TYPE_DOUBLE)
  datetime.iso8601: SoupDate (SOUP_TYPE_DATE)
  base64: GByteArray (SOUP_TYPE_BYTE_ARRAY)
  struct: GHashTable (G_TYPE_HASH_TABLE)
  array: GValueArray (G_TYPE_VALUE_ARRAY)
For structs, use a GHashTable that maps strings to GValue;
soup_value_hash_new() and related methods can help with this.

SoupMessage * soup_xmlrpc_request_new (const char *uri,const char *method_name,...);
Creates an XML-RPC methodCall and returns a SoupMessage, ready to send, for that method call.
The parameters are passed as type/value pairs; ie, first a GType,
and then a value of the appropriate type, finally terminated by
G_TYPE_INVALID.

gboolean soup_xmlrpc_parse_method_response (const char *method_response,int length,GValue *value,GError **error);
Parses method_response and returns the return value in value. If
method_response is a fault, value will be unchanged, and error
will be set to an error of type SOUP_XMLRPC_FAULT, with the error
code containing the fault code, and the error message containing
the fault string. (If method_response cannot be parsed at all,
soup_xmlrpc_parse_method_response() will return FALSE, but error
will be unset.)

gboolean soup_xmlrpc_extract_method_response (const char *method_response,int length,GError **error,GType type,...);
Parses method_response and extracts the return value into
a variable of the correct type.
If method_response is a fault, the return value will be unset,
and error will be set to an error of type SOUP_XMLRPC_FAULT, with
the error code containing the fault code, and the error message
containing the fault string. (If method_response cannot be parsed
at all, soup_xmlrpc_extract_method_response() will return FALSE,
but error will be unset.)

gboolean soup_xmlrpc_parse_method_call (const char *method_call,int length,char **method_name,GValueArray **params);
Parses method_call to get the name and parameters, and returns the
parameter values in a GValueArray; see also
soup_xmlrpc_extract_method_call(), which is more convenient if you
know in advance what the types of the parameters will be.
| 
 | the XML-RPC methodCall string | 
| 
 | the length of method_call, or -1 if it is NUL-terminated | 
| 
 | on return, the methodName from method_call. [out] |

 | on return, the parameters from method_call. [out] | 
| Returns : | success or failure. | 
gboolean soup_xmlrpc_extract_method_call (const char *method_call,int length,char **method_name,...);
Parses method_call to get the name and parameters, and puts
the parameters into variables of the appropriate types.
The parameters are handled similarly to
soup_xmlrpc_build_method_call, with pairs of types and values,
terminated by G_TYPE_INVALID, except that values are pointers to
variables of the indicated type, rather than values of the type.
See also soup_xmlrpc_parse_method_call(), which can be used if
you don't know the types of the parameters.
|

char *              soup_xmlrpc_build_method_response   (GValue *value);
This creates a (successful) XML-RPC methodResponse and returns it
as a string. To create a fault response, use
soup_xmlrpc_build_fault().
The glib type to XML-RPC type mapping is as with
soup_xmlrpc_build_method_call(), qv.
| 
 | the return value | 
| Returns : | the text of the methodResponse, or NULLon error | 
char * soup_xmlrpc_build_fault (int fault_code,const char *fault_format,...);
This creates an XML-RPC fault response and returns it as a string.
(To create a successful response, use
soup_xmlrpc_build_method_response().)
| 
 | the fault code | 
| 
 | a printf()-style format string | 
| 
 | the parameters to fault_format | 
| Returns : | the text of the fault | 
void soup_xmlrpc_set_response (SoupMessage *msg,GType type,...);
Sets the status code and response body of msg to indicate a
successful XML-RPC call, with a return value given by type and the
following varargs argument, of the type indicated by type.
| 
 | an XML-RPC request | 
| 
 | the type of the response value | 
|

void soup_xmlrpc_set_fault (SoupMessage *msg,int fault_code,const char *fault_format,...);
Sets the status code and response body of msg to indicate an
unsuccessful XML-RPC call, with the error described by fault_code
and fault_format.

#define SOUP_XMLRPC_FAULT soup_xmlrpc_fault_quark()
A GError domain representing an XML-RPC fault code. Used with SoupXMLRPCFault (although servers may also return fault codes not in that enumeration).
