passing a filename as a parameter..
How can a filename be passed as a parameter from one function to another function? For instance I have a filname as a string defined as:
char[] = "filename.txt" ;
What would the format of the function that passes it look like and the format of the receiving function look like?
Thanks!

you pass the adress to the first element in the string.
They say that if you play a Windows Install CD backwords, you hear satanic messages. That's nothing; play it forward and it installs Windows.

You could do something like this.Code:#include <stdio.h> void foo(const char *filename) { FILE *file = fopen(filename, "r"); if(file != NULL) { printf("%s: opened\n", filename); fclose(file); printf("%s: closed\n", filename); } else { perror(filename); } } int main(void) { const char filename[] = "filename.txt"; foo(filename); return 0; } /* my output filename.txt: No such file or directory */
