PluginLib_ip_in_reserve_upto Function
int32 PluginLib_ip_in_reserve_upto(
PLUGIN_BUFFER * dataInBuffer,
int32 request,
uint8 ** addr,
int32 * actual
);
Similar to PluginLib_ip_in_reserve_exact , except that rather than shortening the buffer, the amount of buffer space provided is reduced to the amount actually available and *actual is returned. If the buffer is already full, the function sets *actual to zero and returned IPPL_FULL . Otherwise, it returns IPPL_OK .
