call libray function node: read printf messages

[Esther.Lopez]

Hello
I'm calling a function in a dll. This function generates "printf" messages, and I want to know if I can obtain this messages, and how.
Thanks for your help

Hello esther,

you can redirect stdout to a file using "freopen":

FILE *myStdout;
myStdout = freopen("c:\\printf_output.txt", "w", stdout);

if(myStdout != NULL)
printf("\nthis text goes to the file and can be parsed afterwards");
fclose(myStdout);

but you need to have the dll-code. i don't know how to manage this if you only have the dll. maybe you then can create another dll as a wrapper.

best regards
chris
