index(const RWCRegexp& re,size_t* ext,size_t i=0) const;
Regular expression matching. Returns the index greater than or equal to i of the start of the
first pattern that matches the regular expression re. Returns RW_NPOS if there is no such
pattern. The length of the matching pattern is returned in the variable pointed to by ext.
This function is incompatible with strings with embedded nulls. This function may be
incompatible with MBCS strings.
RWCString&
insert(size_t pos, const char* cs);
Insert a copy of the null-terminated string cs into self at byte position pos, thus expanding
the string. Returns a reference to self. This function is incompatible with cs strings with
embedded nulls. This function may be incompatible with cs MBCS strings.
RWCString&
insert(size_t pos, const char* cs, size_t N);
Insert a copy of the first N bytes of cs into self at byte position pos, thus expanding the
string. Exactly N bytes are copied, including any embedded nulls. Hence, the buffer
pointed to by cs must be at least N bytes long. Returns a reference to self.
RWCString&
insert(size_t pos, const RWCString& str);
Insert a copy of the string str into self at byte position pos. Returns a reference to self.
RWCString&
insert(size_t pos, const RWCString& str, size_t N);
Insert a copy of the first N bytes or the length of str (whichever is less) of str into self at
byte position pos. Returns a reference to self.
RWBoolean
isAscii() const;
Returns TRUE if self contains no bytes with the high bit set.
RWBoolean
isNull() const;
Returns TRUE if this is a zero lengthed string (i.e., the null string).
size_t
last(char c) const;
Returns the index of the last occurrence in the string of the character c. Returns
RW_NPOS if there is no such character or if there is an embedded null to the right of c in
self. This function is incompatible with strings with embedded nulls. This function may be
incompatible with MBCS strings.
size_t
last(char c, size_t N) const;
