STRING_TO_WSTRING2

The function converts a variable of the data type STRING into a variable of the data type WSTRING and checks whether the input string is longer than the output string. In this case the string is truncated.

The function returns

TRUE if the conversion of the complete string was possible.
FALSE if the input string is longer than the output string and the result doesn't fit in the given output buffer. The memory requirement for the output string is higher than that for the input string. The string is then truncated.

The function stops the conversion after Parameterlist.cMaxCharacters characters in order to avoid an infinite loop.

FUNCTION STRING_TO_WSTRING2 : BOOL

VAR_INPUT

VAR_INPUT
    pDstWSTRING : POINTER TO WSTRING;
    pSrcSTRING  : POINTER TO STRING;
    nDstSize    : UDINT;
END_VAR

pDstWSTRING: Pointer to the converted WSTRING variable (output string)

pSrcSTRING: Pointer to the STRING variable to be converted (input string)

nDstSize: Size of the resulting WSTRING variable (output string) in bytes. The operator SIZEOF() can be used for the assignment.
