C26165

警告 C26165：可能未能解除锁 <lock>（在函数 <func> 中）。

警告 C26165 类似于警告 C26115，只不过信心更低。例如，函数可以包含注释错误。

示例

下面的代码生成警告C26165.

_Create_lock_level_(LockLevelOne); 
_Create_lock_level_(LockLevelTwo); 

struct LockLevelledStruct
{
    _Has_lock_level_(LockLevelOne) CRITICAL_SECTION a;
    _Has_lock_level_(LockLevelTwo) CRITICAL_SECTION b;
};

_Lock_level_order_(LockLevelOne, LockLevelTwo);

_Acquires_lock_(s->b) void GetLockFunc(LockLevelledStruct* s)
{
    EnterCriticalSection(&s->b);
}

void testLockLevelledStruct(LockLevelledStruct* s) // Warning C26165
{
    EnterCriticalSection(&s->a); 
    GetLockFunc(s);
    LeaveCriticalSection(&s->a);
}

若要更正此警告，请更改前面的示例如下。

_Create_lock_level_(LockLevelOne); 
_Create_lock_level_(LockLevelTwo); 

struct LockLevelledStruct
{
    _Has_lock_level_(LockLevelOne) CRITICAL_SECTION a;
    _Has_lock_level_(LockLevelTwo) CRITICAL_SECTION b;
};

_Lock_level_order_(LockLevelOne, LockLevelTwo);

_Acquires_lock_(s->b) void GetLockFunc(LockLevelledStruct* s)
{
    EnterCriticalSection(&s->b);
}

_Releases_lock_(s->b) void ReleaseLockFunc(LockLevelledStruct* s)
{
    LeaveCriticalSection(&s->b);
}

void testLockLevelledStruct(LockLevelledStruct* s) // OK
{
    EnterCriticalSection(&s->a); 
    GetLockFunc(s);
    ReleaseLockFunc(s);
    LeaveCriticalSection(&s->a);
}
