strrchr

Header: <string.h>

  1. Finds the last occurrence of ch (after conversion to char as if by (char)ch) in the null-terminated byte string pointed to by str (each character interpreted as unsigned char). The terminating null character is considered to be a part of the string and can be found if searching for ‘\0’.

# Declarations

char* strrchr( const char* str, int ch );

/*QChar*/* strrchr( /*QChar*/* str, int ch );

(since C23)

# Parameters

# Return value

Pointer to the found character in str, or null pointer if no such character is found.

# Example

#include <stdio.h>
#include <string.h>
 
int main(void)
{
    char szSomeFileName[] = "foo/bar/foobar.txt";
    char* pLastSlash = strrchr(szSomeFileName, '/');
    char* pszBaseName = pLastSlash ? pLastSlash + 1 : szSomeFileName;
    printf("Base Name: %s", pszBaseName);
}
