Finds the last character equal to none of the characters in the given character sequence. 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 none of characters in
str. 2) Finds the last character equal to none 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 none 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 not equal to
ch.Parameters
| str | - | string identifying characters to search for |
| pos | - | position at which to begin searching |
| count | - | length of character string identifying characters to search for |
| s | - | pointer to a character string identifying characters to search fo |
| ch | - | character identifying characters to search for |
Return value
Position of the found character or npos if no such character is found.
