I am under the impression that the reference returned by NSString's
UTF8String method is valid for the life of the NSString instance which
provided the reference (and further, that the memory of the referenced
C string is freed when the NSString is released). Is this correct?
I have a class with some (statically allocated) class variables. In
the class's -initialize method, I create a retained NSString. I set
one of the class variables to the value returned by -UTF8String (as
sent to that retained NSString). I use this char* value in some C
calls made from instance methods of the class.
The first time an object of the class is instantiated, this works
fine. But it seems that for subsequent instances, although the value
of the char* pointer remains unchanged, the memory it is pointing to
is changed (i.e., no longer a C string representation of the
NSString). So, either the NSString has done something with the memory
pointed to by the initialized reference (i.e., I can't hold onto the
reference as I have been), or somehow the memory is getting corrupt in
some other way. I will look into the latter but only if my assumption
about the former is correct.
TIA.
