ShortArrayToString

It copies part of array into a returned string.

string  ShortArrayToString(
   ushort  array[],      // array
   int     start=0,      // starting position in the array
   int     count=-1      // number of symbols
   );

Parameters

array[]

[in] Array of ushort type (analog of wchar_t type).

start=0

[in] Position, from which copying starts, Default - 0.

count=-1

[in] Number of array elements to copy. Defines the length of a resulting string. Default value is -1, which means copying up to the array end, or till terminal 0.

Return Value

String.

Example:

#define ROW_SIZE 16

ushort ExtShortArray[]={0x2190,0x2191,0x2192,0x2193,0x2194,0x2195,0x2196,0x2197,0x2198,0x2199,0x219A,0x219B,0x219C,0x219D,0x219E,0x219F,
