Function Documentation

int OW_NAMESPACE::Select::select (  const SelectTypeArray &  selarray, UInt32  ms = INFINITE_TIMEOUT )

Select returns as soon as input is available on any of Select_t objects that are in given array. Parameters: selarray  An array of Select_t objects that will be used while waiting for input to become available. ms  The timeout value specified in milliseconds Returns: On success, the index in the selarray of the first Select_t object that input has become available on. SELECT_ERROR on error. SELECT_TIMEOUT if the given timeout value has expired.

int OW_NAMESPACE::Select::selectRW (  SelectObjectArray &  selarray, UInt32  ms = INFINITE_TIMEOUT )

Select returns as soon as input or output is available on any of the Select_t objects that are in given array or the timeout has passed. Parameters: selarray  An array of Select_t objects that will be used while waiting for input or output to become available. ms  The timeout value specified in milliseconds Returns: On success, the number of descriptors available. SELECT_ERROR on error. SELECT_TIMEOUT if the given timeout value has expired. The input and output out parameters are modified to indicate which descriptors are available.
