How to extract filename from path

Question

There should be something elegant in Linux API/POSIX to extract base file name from full path

Answer 1

You can escape slashes to backslash and use this code:

#include 
#include 

int main(void)
{
  char path[] = "C:\\etc\\passwd.c"; //string with escaped slashes
  char temp[256]; //result here
  char *ch; //define this
  ch = strtok(path, "\\"); //first split
  while (ch != NULL) {
      strcpy(temp, ch);//copy result
      printf("%s\n", ch);
      ch = strtok(NULL, "\\");//next split
  }

  printf("last filename: %s", temp);//result filename

  return 0;

}
