Declaration
Boolean CFNetServiceResolve(CFNetParameters
theServiceThe CFNetService to resolve; cannot be
NULL. The resolution will fail if the service doesn’t have a domain, a type, and a name.errorA pointer to a
CFStreamstructure that will be set to an error code and the error code’s domain if an error occurs; orError NULLif you don’t want to receive the error code and its domain.
Return Value
TRUE if an asynchronous service resolution was started or if a synchronous service resolution updated the CFNetService; FALSE if an asynchronous or synchronous resolution failed or if a synchronous resolution was canceled.
Discussion
When resolving a service that runs in asynchronous mode, this function returns TRUE if the CFNetService has a domain, type, and name, and the underlying resolution process was started. Otherwise, this function returns FALSE. Once started, the resolution continues until it is canceled by calling CFNet.
When resolving a service that runs in synchronous mode, this function blocks until the CFNetService is updated with at least one IP address, until an error occurs, or until CFNet is called.
Special Considerations
This function is thread safe.
If the service will be used in asynchronous mode, you must call CFNet before calling this function.
