localString returns a structur by value and no pointer. #1
Description
localString returns a structur by value and no pointer. Therefore the example is wrong:
#define SIZE 40 <--- the LString can never grow longer than 39 chars
static char buff[SIZE] = "Hello";
LString *hello = localString(buff, SIZE);
...
lstringchcat(hello, " World !");
} <--- automatic deallocation at the end of the scope
Warning: The following does not work (because localString does
not allocate memory):
LString *hello = localString("Hello World", SIZE);
In my opinion it must be:
#define SIZE 40 <--- the LString can never grow longer than 39 chars
static char buff[SIZE] = "Hello";
LString hello = localString(buff, SIZE);
...
lstringchcat(&hello, " World !");
} <--- automatic deallocation at the end of the scope
Warning: The following does not work (because localString does
not allocate memory):
LString hello = localString("Hello World", SIZE);
