Warning C6386
Buffer overrun: accessing 'buffer name', the writable size is 'size1' bytes, but 'size2' bytes may be written: Lines: x, y
Remarks
This warning indicates that the writable extent of the specified buffer might be smaller than the index used to write to it. This defect can cause buffer overrun.
Code analysis name: WRITE_OVERRUN
Example
The following code generates both this warning and C6201:
#define MAX 25
void f ( )
{
char ar[MAX];
// code ...
ar[MAX] = '\0';
}
To correct both warnings, use the following code:
#define MAX 25
void f ( )
{
char a[MAX];
// code ...
a[MAX - 1] = '\0';
}
