## Detailed Description

Functions, types, and enums that implement the Sanitizer Callback API.

## 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.

## Function Documentation

SanitizerResult SANITIZERAPI sanitizerEnableAllDomains | ( | uint32_t | enable,
|  | Sanitizer_SubscriberHandle | subscriber |
| ) |  |  |

Enable or disable all callbacks in all domains.

Note:
  Thread-safety: a subscriber must serialize access to sanitizerGetCallbackState, sanitizerEnableCallback, sanitizerEnableDomain, and sanitizerEnableAllDomains. 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:

  | SANITIZER_SUCCESS | on success
  | SANITIZER_ERROR_NOT_INITIALIZED | if unable to initialize the sanitizer
  | SANITIZER_ERROR_INVALID_PARAMETER | if `subscriber` is invalid

SanitizerResult SANITIZERAPI sanitizerEnableCallback | ( | uint32_t | enable,
|  | Sanitizer_SubscriberHandle | subscriber,
|  | Sanitizer_CallbackDomain | domain,
|  | Sanitizer_CallbackId | cbid |
| ) |  |  |

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:

  | enable | New enable state for the callback. Zero disables the callback, non-zero enables the callback
  | subscriber | - Handle of the initialized subscriber
  | domain | The domain of the callback
  | cbid | The ID of the callback

Return values:

  | SANITIZER_SUCCESS | on success
  | SANITIZER_ERROR_NOT_INITIALIZED | if unable to initialize the sanitizer
  | SANITIZER_ERROR_INVALID_PARAMETER | if `subscriber`, `domain` or `cbid` is invalid

SanitizerResult SANITIZERAPI sanitizerEnableDomain | ( | uint32_t | enable,
|  | 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
  | subscriber | - Handle of the initialized subscriber
  | domain | The domain of the callback

Return values:

  | SANITIZER_SUCCESS | on success
  | SANITIZER_ERROR_NOT_INITIALIZED | if unable to initialize the sanitizer
  | SANITIZER_ERROR_INVALID_PARAMETER | if `subscriber` or `domain` is invalid

SanitizerResult SANITIZERAPI sanitizerGetCallbackState | ( | uint32_t * | enable,
|  | Sanitizer_SubscriberHandle | subscriber,
|  | Sanitizer_CallbackDomain | domain,
|  | 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
  | domain | The domain of the callback
  | cbid | The ID of the callback

Return values:

  | SANITIZER_SUCCESS | on success
  | SANITIZER_ERROR_NOT_INITIALIZED | if unable to initialize the sanitizer
  | SANITIZER_ERROR_INVALID_PARAMETER | if `enabled` is NULL, or if `subscriber`, `domain` or `cbid` is invalid.

SanitizerResult SANITIZERAPI sanitizerSubscribe | ( | Sanitizer_SubscriberHandle * | subscriber,
|  | Sanitizer_CallbackFunc | callback,
|  | void * | userdata |
| ) |  |  |

Initialize a callback subscriber with a callback function and (optionally) a pointer to user data. The returned subscriber handle can be used to enable and disable the callback for specific domains and callback IDs.

Note:
  Only one subscriber can be registered at a time.

  This function does not enable any callbacks.

  Thread-safety: this function is thread safe.

Parameters:

  | subscriber | Returns handle to initialize subscriber
  | callback | The callback function
  | userdata | A pointer to user data. This data will be passed to the callback function via the `userdata` parameter

Return values:

  | SANITIZER_SUCCESS | on success
  | SANITIZER_ERROR_NOT_INITIALIZED | if unable to initialize the sanitizer
  | SANITIZER_ERROR_MAX_LIMIT_RACHED | if there is already a sanitizer subscriber
  | SANITIZER_ERROR_INVALID_PARAMETER | if `subscriber` is NULL

SanitizerResult SANITIZERAPI sanitizerUnsubscribe | ( | Sanitizer_SubscriberHandle | subscriber | ) |

Removes a callback subscriber so that no future callback will be issued to that subscriber.

Note:
  Thread-safety: this function is thread safe.

Parameters:

  | subscriber | Handle to the initialized subscriber

Return values:

  | SANITIZER_SUCCESS | on success
  | SANITIZER_ERROR_NOT_INITIALIZED | if unable to initialize the sanitizer
  | SANITIZER_ERROR_INVALID_PARAMETER | if `subscriber` is NULL or not initialized
