%MULTIDFPRINTF Print formatted text to multiple streams
|
|
%
|
|
% COUNT = MULTIDFPRINTF(IDVEC, FORMAT, A, ...) performs formatted output
|
|
% to multiple streams such as console and files. FORMAT is the format string
|
|
% as used by sprintf and fprintf. A is the array of elements, to which the
|
|
% format will be applied similar to sprintf and fprint.
|
|
%
|
|
% IDVEC is a vector (1xN) of file descriptors and COUNT is a vector (1xN) of
|
|
% the number of bytes written to each file.
|
|
%
|
|
% Notes::
|
|
% - To write to the consolde use the file identifier 1.
|
|
%
|
|
% Example::
|
|
% % Create and open a new example file:
|
|
% fid = fopen('exampleFile.txt','w+');
|
|
% % Write something to the file and the console simultaneously:
|
|
% multidfprintf([1 FID],'% s % d % d % d!\n','This is a test!',1,2,3);
|
|
% % Close the file:
|
|
% fclose(FID);
