strrchr - string scanning operation
char *strrchr(const char *s, int c);
[CX] The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of POSIX.1-2017 defers to the ISO C standard.
The strrchr() function shall locate the last occurrence of c (converted to a char) in the string pointed to by s. The terminating NUL character 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.
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; ...
