# ACE\_TSS\_Read\_Guard(3)

This class is similar to class ACE\_TSS\_Guard, though it acquires/releases a read lock automatically (naturally, the ACE\_LOCK it is instantiated with must support the appropriate API).

## NAME

ACE\_TSS\_Read\_Guard -  This class is similar to class ACE\_TSS\_Guard, though it acquires/releases a read lock automatically (naturally, the ACE\_LOCK it is instantiated with must support the appropriate API).

## SYNOPSIS

```
#include <ace/Synch_T.h>
template<class ACE_LOCK>
class ACE_TSS_Read_Guard : public ACE_TSS_Guard<ACE_LOCK>
{
  public:
    ACE_TSS_Read_Guard (ACE_LOCK &lock, int block = 1);
    int acquire_read (void);
    int acquire (void);
    int tryacquire_read (void);
    int tryacquire (void);
    void dump (void) const;
};
```

## Initialization method.

```
ACE_TSS_Read_Guard (ACE_LOCK &lock, int block = 1);
```

Implicitly and automatically acquire the thread-specific read lock.

## Lock accessors.

```
int acquire_read (void);
```

Explicitly acquire the thread-specific read lock.

```
int acquire (void);
```

Explicitly acquire the thread-specific read lock.

```
int tryacquire_read (void);
```

Conditionally acquire the thread-specific read lock (i.e., won't block).

```
int tryacquire (void);
```

Conditionally acquire the thread-specific read lock (i.e., won't block).

## Utility methods.

```
void dump (void) const;
```

Dump the state of an object.

ACE\_ALLOC\_HOOK\_DECLARE; Declare the dynamic allocation hooks.
