I'm sick of this warning! Here's the code
1
struct passwd *pwd; 
2
3
code In function printLine:
4
gid_t gid = statbuf.st_gid;
5
        pwd = getgrgid(gid);
6
        if(pwd != NULL)
7
            printf("%s]", pwd->pw_name);
8
        else
9
            printf("%d]", statbuf.st_gid);
All prints correctly when executed. What needs to be corrected so that 
the selection disappears?

struct group *

pwd seems to be of type

  struct passwd *

but getgrgid() returns

  struct group *

The first three elements of the two structs are similar, thus the code
still works.
