Summary

Types

Name	Description
typedef enum OH_Drawing_ErrorCode OH_Drawing_ErrorCode	Defines an enum for the error codes that may be generated by the module.

Enums

Name	Description
OH_Drawing_ErrorCode { OH_DRAWING_SUCCESS = 0, OH_DRAWING_ERROR_NO_PERMISSION = 201, OH_DRAWING_ERROR_INVALID_PARAMETER = 401, OH_DRAWING_ERROR_PARAMETER_OUT_OF_RANGE = 26200001,OH_DRAWING_ERROR_ALLOCATION_FAILED = 26200002 }	Enumerates the error codes that may be generated by the module.

Functions

Name	Description
OH_Drawing_ErrorCode OH_Drawing_ErrorCodeGet ()	Obtains the latest error code of the module. After the function is successfully executed, the error code returned by this function will not be modified.
void OH_Drawing_ErrorCodeReset (void)	Resets the error code of this module to OH_DRAWING_SUCCESS. When a function that does not return an error code fails, the error code obtained through OH_Drawing_ErrorCodeGet is reset to the corresponding error number. However, it is not reset to OH_DRAWING_SUCCESS for a successful operation. By calling this function, you can manually reset the error code to OH_DRAWING_SUCCESS, avoiding interference between different functions and simplifying the debugging process.
