Fgets compilation error
I'm stuck with what seems a beginner's compilation error:
My simple program:
#include <stdlib.h>
#include <stdio.h>
#include "Tiles_Circular_Linked_List.h"
#define MAX_LINE_LENGTH 128;
int main(int argc, char **argv) {
struct node *head_tail;
FILE *file;
/*char filename[] = "/home/student/Desktop/Studies/C/testing_fodder/tiles";*/
argv++; /*go to second character-array argument*/
file = fopen(*argv, "r");
char *curr_line;
fgets(curr_line, MAX_LINE_LENGTH, file);
return 0;
}
I try to compile it using this command:
gcc -g -Wall -ansi launch_tiles.c -o tiles_prog
and get these errors:
launch_tiles.c: In function 'main':
launch_tiles.c:17:19: error: expected ')' before ';' token
launch_tiles.c:17:19: error: too few arguments to function 'fgets' /usr/include/stdio.h:628:14: note: declared here
launch_tiles.c:9:8: warning: variable 'file' set but not used [-Wunused-but-set-variable]
launch_tiles.c:8:15: warning: unused variable 'head_tail' [-Wunused-variable]
I am interested about the errors, not the warnings.
I can count three arguments that I pass to fgets
and don't understand where do I miss parentheses so what's the problem?
Thanks!
change
#define MAX_LINE_LENGTH 128;
to
#define MAX_LINE_LENGTH 128
(without the ;
). Easy mistake to make.
The C preprocessor does very simple, textual substitution, so with the wrongly-defined macro, you end up with
fgets(curr_line, 128;, file);
which is obviously a syntax error.
