EXAMPLES
Finding the Base Name of a File
The following example uses strrchr() to get a pointer to the base name
of a file. The strrchr() function searches backwards through the name
of the file to find the last ’/’ character in name. This pointer (plus
one) will point to the base name of the file.
#include <string.h>
...
const char *name;
char *basename;
...
basename = strrchr(name, ’/’) + 1;
