printf() and fprintf() with DLL-Files

[mb]

Hello everybody,

I'm building MATLAB V.4 MEX-Files with Borland C++ 3.1 and I have some
problems using printf() and fprint() in C.
These commands work correctly with %d and %x. But for all floating-point
data-types ,for example %f, %g, these commands don't work.
Can anybody tell me where the problem is ?

Thanks,
Markus Glaser

Hi,

Believe it or not, these format specifiers are not supported in 16-bit
DLLs. There is a file on our ftp server, I think called printdll,
which works around this by using a MEX-file which calls back into
MATLAB to do the formatting.

This limitation does not exist for 32-bit DLLs, which are supported
in MATLAB 5.x

HTH.
