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:
| 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.
int GrantPermission (const char * identifier, const char * permName )
Description:
Grants a specified permission to the application.
Parameters:
| 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.
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:
| 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.
int QueryPermission (const char * identifier, [PermissionSaved](PermissionSaved.md) ** permissions, int * permNum )
Description:
Queries all permissions requested by the application and checks whether these permissions are granted.
Parameters:
| 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.
int RequestPermission (int taskID, const char * permissionName )
Description:
Requests a specified permission.
Parameters:
| 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.
int RevokePermission (const char * identifier, const char * permName )
Description:
Revokes a specified permission from the application.
Parameters:
| 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.
