function
<cstring>

strrchr

const char * strrchr ( const char * str, int character );      char * strrchr (       char * str, int character );
Locate last occurrence of character in string
Returns a pointer to the last occurrence of character in the C string str.

The terminating null-character is considered part of the C string. Therefore, it can also be located to retrieve a pointer to the end of a string.

Parameters

str
C string.
character
Character to be located. It is passed as its int promotion, but it is internally converted back to char.

Return Value

A pointer to the last occurrence of character in str.
If the character is not found, the function returns a null pointer.

Portability

In C, this function is only declared as:

char * strrchr ( const char *, int );

instead of the two overloaded versions provided in C++.
