Library FunctionsSTRRCHR, STRRICHRSynopsis#include char * strrchr (char * s, int c)char * strrichr (char * s, int c)DescriptionThe strrchr() function is similar to the strchr() function, but searches from the end of the stringrather than the beginning, i.e. it locates the last occurrence of the character c in the null terminatedstring s. If successful it returns a pointer to that occurrence, otherwise it returns NULL.The strrichr() function is the case-insensitive version of this function.Example#include #include voidmain (void){char * str = "This is a string.";}while(str != NULL) {printf( "%s\n", str );str = strrchr( str+1, ’s’);}See Alsostrchr(), strlen(), strcmp(), strcpy(), strcat()Return ValueA pointer to the character, or NULL if none is found.214
