Compiler Warning (level 4) C4703
Visual Studio 2012
Potentially uninitialized local pointer variable 'name' used
The local pointer variable name might have been used without being assigned a value. This could lead to unpredictable results.
The following code generates C4701 and C4703.
#include <malloc.h> void func(int size) { void* p; if (size < 256) { p = malloc(size); } if (p != nullptr) // C4701 and C4703 free(p); } void main() { func(9); }
c:\src\test.cpp(10) : warning C4701: potentially uninitialized local variable 'p' usedc:\src\test.cpp(10) : warning C4703: potentially uninitialized local pointer variable 'p' used
To correct this warning, initialize the variable as shown in this example:
#include <malloc.h> void func(int size) { void* p = nullptr; if (size < 256) { p = malloc(size); } if (p != nullptr) free(p); } void main() { func(9); }
