# smfi_setpriv

SYNOPSIS |
    #include <libmilter/mfapi.h>
    int smfi_setpriv(
    	SMFICTX *ctx,
    	void *privatedata
    );
Set the private data pointer for this connection.
DESCRIPTION |
Called When | smfi_setpriv may be called in any of the xxfi_* callbacks.
Effects | Sets the private data pointer for the context ctx.
ARGUMENTS |
Argument | Description
--- | ---
ctx | Opaque context structure.
privatedata | Pointer to private data. This value will be returned by subsequent calls to smfi_getpriv using ctx.
RETURN VALUES | smfi_setpriv returns MI_FAILURE if ctx is an invalid context. Otherwise, it returns MI_SUCCESS.
NOTES | There is only one private data pointer per connection; multiple calls to smfi_setpriv with different values will cause previous values to be lost. Before a filter terminates it should release the private data and set the pointer to NULL.
