It does return a null terminated char const *, although please notice that 
this pointer may point to garbage on any subsequent line of your code, if the 
source QString was destroyed.

Thus, I'd always do this (unless I'm the one owning the QString):

char mybuf[512];
strncpy(mybuf, selectedFile().latin1(), sizeof(mybuf) - 1);
mybuf[sizeof(mybuf) - 1] = 0;
// sizeof()-1 so that the mybuf will always be zero-terminated
// even if latin1() returns a 512- or longer string
