The Code Analysis tool detects some situations in which buffer overruns occur, including array bounds violations.

For more information about Code Analysis warnings, see this Microsoft Web site.

The following warnings are reported in this category:

Warning Description

C6029

Possible buffer overrun in call to <function>.

C6057

Buffer overrun due to number of characters/number of bytes mismatch in call to <function>.

C6201

Buffer overrun for <variable>, which is possibly stack allocated: index <name> is out of valid index range <min> to <max>

C6202

Buffer overrun for <variable>, which is possibly stack allocated, in call to <function>: length <size> exceeds buffer size <max>

C6203

Buffer overrun for buffer <variable> in call to <function>: length <size> exceeds buffer size

C6204

Possible buffer overrun in call to <function>: use of unchecked parameter <variable>

C6209

Using 'sizeof<variable1>' as parameter <number> in call to <function> where <variable2> may be an array of wide characters, did you intend to use character count rather than byte count?

C6292

Ill-defined for-loop: counts up from maximum

C6293

Ill-defined for-loop: counts down from minimum

C6294

Ill-defined for-loop: initial condition does not satisfy test. Loop body not executed

C6295

Ill-defined for-loop: <variable> values are of the range "min" to "max". Loop executed indefinitely

C6296

Ill-defined for-loop: Loop body only executed once
