@ -116,7 +116,7 @@ the ``F()`` macro and possibly the FPSTR() macro. These are defined in `WString.
#define FPSTR(pstr_pointer) (reinterpret_cast<const __FlashStringHelper *>(pstr_pointer))
#define F(string_literal) (FPSTR(PSTR(string_literal)))
So ``FSPTR()`` takes a PROGMEM pointer to a string and casts it to this
So ``FPSTR()`` takes a PROGMEM pointer to a string and casts it to this
``__FlashStringHelper`` class. Thus if you have defined a string as
above ``xyz`` you can use ``FPSTR()`` to convert it to
``__FlashStringHelper`` for passing into functions that take it.
