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 could use strstr in case you are interested in the directory names too:

char *path ="ab/cde/fg.out";
char *ssc;
int l = 0;
ssc = strstr(path, "/");
do{
    l = strlen(ssc) + 1;
    path = &path[strlen(path)-l+2];
    ssc = strstr(path, "/");
}while(ssc);
printf("%s\n", path);
