Upon successful completion, strrchr() shall return a pointer to the byte or a null pointer if c does not occur in the string.

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; ...
