Method FastBuffer-1.GetString

Overload

Gets API result as string, or allocates bigger buffer if old buffer was too small. This function can be used when T is char.

public bool GetString(int r, out string s, BSFlags flags = 0, string sDefault = null)
Parameters
r  (int)

The return value of the called Windows API function, if it returns string length or required buffer length. Or you can call FastBuffer<T>.FindStringLength.
s  (string)

Receives the result string if succeeded, else sDefault (default null).
flags  (BSFlags)

Use if the API function isn't like this:

  • If succeeds, returns string length without the terminating '\0' character.
  • If buffer too small, returns required buffer length.
  • If fails, returns 0.
sDefault  (string)

Set s = this string if buffer too small or r < 1 or if the retrieved string == this string (avoid creating new string).
Returns
bool

If r > n, calls More(r); and returns false. Else creates new string of r length and returns true.
