Hello everyone,
I'm writing a program that runs an execution file from within the program.
When the execution file runs, some text is output in the command screen, which I would like to be able to capture in an array.
I am trying to avoid redirecting the command output to a file and then capturing it from there.
Any help would be very much appreciated! Thanks.
Something like
Code:FILE *fp = popen("someCommand","r"); while ( fgets(buff,sizeof(buff),fp) != NULL ) { // store buff in your array } pclose(fp);
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Thanks Salem!
Do you know what library the 'popen' function is under? I'm compiling it using LabWindows, and it doesn't seem to recognize that function.
The header file that needs included might be "stdio.h" and the function might be named "_popen" instead of "popen".
Not all C Compilers have "popen" functions.
No idea if you need to link with a library; but, you often need to define a macro to use the function.
