Description

rindex- string operations

These functions operate on NULL-terminated strings. They do not check for overflow of any receiving string.

index and rindex return a pointer to the first (last) occurrence of character c in string s, or a NULL pointer if c does not occur in the string. The NULL character terminating a string is considered to be part of the string.
