"Returns the AnsiString converted to null-terminated character array.

char* __fastcall c_str() const;

Description

c_str returns a pointer a null-terminated character array containing the
same characters as the AnsiString. If the AnsiString is unassigned, c_str
returns an empty string ("").

Usually, the value returned by c_str points to the internal character array
referenced by the data property. This pointer is valid until the string is
next modified (for example when the SetLength method is called or the
AnsiString goes out of scope). However, if the internal array is NULL, c_str
returns a pointer to a string literal.

The c_str method is intended primarily for reading the value of the
AnsiString. To modify the string's value, use the [] operator or AnsiString
methods such as Insert and Delete." - Citat slut
