SDPMessage.init_

Initialize msg so that its contents are as if it was freshly allocated with [gstsdp.sdpmessage.SDPMessage.new_]. This function is mostly used to initialize a message allocated on the stack. [gstsdp.sdpmessage.SDPMessage.uninit] undoes this operation.

When this function is invoked on newly allocated data (with malloc or on the stack), its contents should be set to 0 before calling this function.
