For more information, see the description of Global in the reference manual.</p> <p>Note that the functions below perform an RPC using an open file descriptor provided by the caller. This file descriptor must not be used for other traffic during the global operation or the function may receive unexpected data and fail.</p> </p></div> <h3>EXPORTS</h3> <p><a name="erl_global_names"><span class="bold_code">char ** erl_global_names(fd,count)</span></a><br></p> <div class="REFBODY"> <p>Types:</p> <div class="REFTYPES"> <span class="bold_code">int fd;</span><br> </div> <div class="REFTYPES"> <span class="bold_code">int *count;</span><br> </div> </div> <div class="REFBODY"><p> <p>Retrieve a list of all known global names. </p> <p><span class="code">fd</span> is an open descriptor to an Erlang connection. </p> <p><span class="code">count</span> is the address of an integer, or NULL. If <span class="code">count</span> is not NULL, it will be set by the function to the number of names found. </p> <p>On success, the function returns an array of strings, each containing a single registered name, and sets <span class="code">count</span> to the number of names found. The array is terminated by a single NULL pointer.
