Question

This is the line i’m trying to split, from the start until the :, eat any whitespace and from there onwards:

file1: file2,file3,file4

And my code is:

while(fscanf(fp,"%s: %s",map[i].name, map[i].filesNeeded) == 1)
{
   printf("%s %s\n",map[i].name, map[i].filesNeeded);
   i++;
}

The second parameter is never saved. the result is:

file1: 
file2,file3,file4

instead of:

file1 file2,file3,file4

Answer 1

Firstly, fscanf will increment the return for each item matched, so it should be == 2.

Also, you will want to use %[^:] instead of %s as the %s won’t know when to stop.

int main(int argc, char** argv)
{
  char test[] = "one: two,three";

  char part1[20];
  char part2[20];

  printf("%i\n", sscanf(test, "%[^:]: %s", part1, part2));

  printf("%s %s\n", part1, part2);
}

Output:

2
one two,three
