Finds the last character equal to one of characters in the given character sequence. Exact search algorithm is not specified. The search considers only the interval [0; pos]. If the character is not present in the interval, npos will be returned.
1) Finds the last character equal to one of characters in
str
.
2) Finds the last character equal to one of characters in the first
count
characters of the character string pointed to by s
. s
can include null characters.
3) Finds the last character equal to one of characters in character string pointed to by
s
. The length of the string is determined by the first null character.
4) Finds the last character equal to
ch
.
