This data type is equivalent to char *.If you are working with string-based instrument control, it may be easier to pass an array of 8-bit integers than C strings because of the possibility of NULL values in the string. When you place a Call Library Function Node, double-click it to ...

Pointers to char are oftenused to represent strings. To represent a valid byte string, a pointer must be pointing at a char that is an element of an array of char, and there must be a char with the value zero at some index greater or equal to the index of the element referenced by...
