## Typedef Documentation

typedef void(SANITIZERAPI * Sanitizer_CallbackFunc)(void *userdata, Sanitizer_CallbackDomain domain, Sanitizer_CallbackId cbid, const void *cbdata)

Function type for a callback. The type of the data passed to the callback in `cbdata` depends on the domain. If `domain` is SANITIZER_CB_DOMAIN_DRIVER_API or SANITIZER_CB_DOMAIN_RUNTIME_API the type of `cbdata` will be Sanitizer_CallbackData. If `domain` is SANITIZER_CB_DOMAIN_RESOURCE the type of `cbdata` will be dependent on cbid. Refer to Sanitizer_ResourceContextData, Sanitizer_ResourceStreamData, Sanitizer_ResourceModuleData and Sanitizer_ResourceMemoryFlags documentations. If `domain` is SANITIZER_CB_DOMAIN_SYNCHRONIZE the type of `cbdata` will be Sanitizer_SynchronizeData. If `domain` is SANITIZER_CB_DOMAIN_LAUNCH the type of `cbdata` will be Sanitizer_LaunchData. If `domain` is SANITIZER_CB_DOMAIN_MEMCPY the type of `cbdata` will be Sanitizer_MemcpyData. If `domain` is SANITIZER_CB_DOMAIN_MEMSET the type of `cbdata` will be Sanitizer_MemsetData. If `domain` is SANITIZER_CB_DOMAIN_BATCH_MEMOP the type of `cbdata` will be Sanitizer_BatchMemopData.

For example, if sanitizerGetCallbackState(sub, d, *) and sanitizerEnableAllDomains(sub) are called concurrently, the results are undefined.

Parameters:

  | enable | New enable state for all callbacks in all domains. Zero disables all callbacks, non-zero enables all callbacks.
  | subscriber | - Handle of the initialized subscriber

Return values:

| ) |  |  |

Enable or disable callbacks for a subscriber for a specific domain and callback ID.

Note:
  Thread-safety: a subscriber must serialize access to sanitizerGetCallbackState, sanitizerEnableCallback, sanitizerEnableDomain, and sanitizerEnableAllDomains. For example, if sanitizerGetCallbackState(sub, d, c) and sanitizerEnableCallback(sub, d, c) are called concurrently, the results are undefined.

Parameters:

|  | Sanitizer_SubscriberHandle | subscriber,
|  | Sanitizer_CallbackDomain | domain |
| ) |  |  |

Enable or disable all callbacks for a specific domain.

Note:
  Thread-safety: a subscriber must serialize access to sanitizerGetCallbackState, sanitizerEnableCallback, sanitizerEnableDomain, and sanitizerEnableAllDomains. For example, if sanitizerGetCallbackEnabled(sub, d, *) and sanitizerEnableDomain(sub, d) are called concurrently, the results are undefined.

Parameters:

  | enable | New enable state for all callbacks in the domain. Zero disables all callbacks, non-zero enables all callbacks

|  | Sanitizer_CallbackId | cbid |
| ) |  |  |

Returns non-zero in `*enable` if the callback for a domain and callback ID is enabled, and zero if not enabled.

Note:
  Thread-safety: a subscriber must serialize access to sanitizerGetCallbackState, sanitizerEnableCallback, sanitizerEnableDomain, and sanitizerEnableAllDomains. For example, if sanitizerGetCallbackState(sub, d, c) and sanitizerEnableCallback(sub, d, c) are called concurrently, the results are undefined.

Parameters:

  | enable | Returns non-zero if callback enabled, zero if not enabled
  | subscriber | Handle to the initialized subscriber
