Syntax

  [in]           WS_TYPE_MAPPING typeMapping,
  [in]           WS_TYPE         type,
  [in, optional] const void      *typeDescription,
  [in]           WS_WRITE_OPTION writeOption,
                 const void      *value,
  [in]           ULONG           valueSize,
  [in, optional] WS_ERROR        *error
);

Parameters

[in] writer

The writer to write the value to.

[in] typeMapping

Describes how the type maps to the XML that is being written.

[in] type

The type of the value to serialize.

[in, optional] typeDescription

Additional information about the type. Each type has a different description structure. This may be NULL, depending on the WS_TYPE.

[in] writeOption

Whether the value is required, and how the value is allocated. See WS_WRITE_OPTION for more information.

This parameter must have one of the following values:

value

A pointer to the value to serialize.

[in] valueSize

The size of the value being serialized.

[in, optional] error

Specifies where additional error information should be stored if the function fails.

Return value

One or more arguments are invalid.

Remarks

See WS_TYPE_MAPPING for how to use this function to write values in elements and attributes.

If the API fails, the state of input writer becomes undefined. The only APIs that may be used on the writer if this occurs are WsSetOutput and WsSetOutputToBuffer to return the writer to a usable state, or WsFreeWriter to free the writer.
