Search for a word in file line by line in C programming

I am trying to write code to search for a word in a file line by line and print the line containing the word. Functions fgets and getline didn't seem to work.

void FindWord(char *word , char *file){
   char *line ;
   line = (char*)malloc(1024) ;
   int fd ;
   fd = open(file , O_RDONLY );
   while (fgets(line , sizeof(line) ,fd )!= NULL)
   {
      if (strstr(line , word )!= NULL)
      {
         printf("%s",line);
      }
   }
}
