PureBasic Forums - English

This was a discussion somewhere else in the forum in the past, in a different aspect, but I can't find it now so i'll re-ask the question in a more direct manner then what i remember that other discussion being:

How come PB string functions like FindString, StringByteLength, etc....exclude the terminating null of a string in their returns?

a string "123456" - Len("123456") = 6 - StringByteLength("123456") = 6 - FindString("123456", Chr(0), 1) = 0 (or FindString("123456", #Null$, 1) = 0)

strings in PB consume memory at "string length + 1" (so I assume strings in PB automatically include a terminating null)

Because a PB string it's a particular kind of memory buffer, cannot contain a $00 by definition.
$00 is the termination char. It something beyond the string. It's not part of the string.
It's simply a convention.

SizeOf(Character) is your friend.

PrintN is nice. The sky is blue.
