How I can print to stderr in C?

The syntax is almost the same as printf. With printf you give the string format and its contents i.e.:

printf("my %s has %d chars\n", "string format", 30);

With fprintf it is the same, except now you are also specifying the place to print to:

File *myFile;
fprintf( myFile, "my %s has %d chars\n", "string format", 30);

Or in your case:

fprintf( stderr, "my %s has %d chars\n", "string format", 30);
