processError.m

Go to the documentation of this file.

function retVal = processError(mException, sockfd, signal)
% PROCESSERROR - Processes a MATLAB exception
%
%   retVal = processError(mException, sockfd, signal) processes
%   a MATLAB exception. 
%   The function writes an error message to the console.
%   Next, if the BCVTB library can be loaded
%   and if sockfd is not a negative number, then 
%   this function sends 'signal' to the socket.
%   
%   If sending a message to the socket was successful, then
%   'retVal' will be zero.
%  
%   This function will also load the library libbcvtb unless it is
%   already loaded.
