| const char* strrchr( const char* str, int ch ); |
||
| char* strrchr( char* str, int ch ); |
||
Finds the last occurrence of ch (after conversion to char) in the byte string pointed to by str. The terminating null character is considered to be a part of the string and can be found if searching for '\0'.

[edit] Parameters
| str | - | pointer to the null-terminated byte string to be analyzed |
| ch | - | character to search for |
[edit] Return value
Pointer to the found character in str, or null pointer if no such character is found.
[edit] Example
Run this code
#include <cstring> #include <iostream> int main() { char input[] = "/home/user/hello.c"; char* output = std::strrchr(input, '/'); if (output) std::cout << output + 1 << '\n'; }
Output:
hello.c
