Re: [Opalvoip-user] [PTLIB] Can PString.GetSize() return negative values?

[Robert J. <ro...@vo...>]

It is never negative.

On many platforms PINDEX is defined as size_t which is typically unsigned.

Hello


I have simple question: Can PString.GetSize() return negative values?

Looked into documentation, but found only that it returns PINDEX (aka int) value.

But is it safe to compare it with unsigned value?


Thank you.
