Finding the Base Name of a File
strrchr - string scanning operation
char *strrchr(const char *s, int c);
The strrchr() function shall locate the last occurrence of c (converted to a char) in the string pointed to by s. The terminating null byte is considered to be part of the string.
Upon successful completion, strrchr() shall return a pointer to the byte or a null pointer if c does not occur in the string.
No errors are defined.
The following sections are informative.
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; ...
