CheckPermission()


1. int CheckPermission (int taskID, const char * permissionName )

Description:

Checks whether the caller (generally a third-party application) has a specified permission of a system service API.

Parameters:

Name	Description
taskId	Indicates the process ID of the caller. The range is [0, INT_MAX].
permissionName	Indicates the pointer to the permission name. For details, see the developer documentation.

Returns:

Returns 1 if the caller has the permission; returns 0 otherwise.

GrantPermission()


1. int GrantPermission (const char * identifier, const char * permName )

Description:

Grants a specified permission to the application.

Parameters:

Name	Description
identifier	Indicates the pointer to the application bundle name.
permName	Indicates the pointer to the permission name. For details, see the developer documentation.

Returns:

Returns 0 if the permission is successfully granted; returns an error code defined in PmsErrorCode otherwise.

GrantRuntimePermission()


1. int GrantRuntimePermission (int taskID, const char * permissionName )

Description:

Grants a specified runtime permission to an application.

This function applies to sensitive permissions that can be granted to the application only when the application is running.

Parameters:

Name	Description
taskId	Indicates the process ID of the application. The range is [0, INT_MAX].
permissionName	Indicates the pointer to the permission name. For details, see the developer documentation.

Returns:

Returns 0 if the permission is successfully granted; returns an error code defined in PmsErrorCode otherwise.

QueryPermission()


1. int QueryPermission (const char * identifier, [PermissionSaved]($api-api-SmartVision-Devices-PermissionSaved.md) ** permissions, int * permNum )

Description:

Queries all permissions requested by the application and checks whether these permissions are granted.

Parameters:

Name	Description
identifier	Indicates the pointer to the application bundle name.
permissions	Indicates the double pointer to the array of permissions. You need to pass the PermissionSaved pointer and release it after finishing using it.
permNum	Indicates the pointer to the number of permissions in the array, which is an integer.

Returns:

Returns 0 if the operation is successful; returns an error code defined in PmsErrorCode otherwise.

RequestPermission()


1. int RequestPermission (int taskID, const char * permissionName )

Description:

Requests a specified permission.

Parameters:

Name	Description
taskId	Indicates the process ID of the application. The range is [0, INT_MAX].
permissionName	Indicates the pointer to the permission name. For details, see the developer documentation.

Returns:

Returns 0 if the operation is successful; returns an error code defined in PmsErrorCode otherwise.

RevokePermission()


1. int RevokePermission (const char * identifier, const char * permName )

Description:

Revokes a specified permission from the application.

Parameters:

Name	Description
identifier	Indicates the pointer to the application bundle name.
permName	Indicates the pointer to the permission name. For details, see the developer documentation.

Returns:

Returns 0 if the permission is successfully revoked; returns an error code defined in PmsErrorCode otherwise.
