A method and system for nearly immediately trapping a failure-to-check-a-return-value error in a computer program. Modern processor architectures, such as the Intel® IA-64 processor architecture, provide for control speculation of load instructions, including 1-bit NAT registers, associated with general registers, that indicate occurrences of deferred exceptions arising during execution of control-speculative load instructions targeting the corresponding general registers. One embodiment of the present invention employs the NAT registers associated with general-purpose registers to distinguish special values, often indicating error conditions, stored in general-purpose registers serving to store the return values of functions and routines.

Embodiments of the present invention provide a link switching method and a device, wherein the method and the device are applied to a mobile terminal. The method comprises the steps of turning on a first transfer mode, and respectively connecting a first wireless access point with a target terminal so as to transmit communication data between the target terminal and the first wireless access point; detecting a front-end communication link, wherein the front-end communication link is a link between the mobile terminal and the first wireless access point; upon detecting the abnormal communication state of the front-end communication link, turning off the first transfer mode; turning on a second transfer mode, and respectively connecting a second wireless access point with the target terminal so as to transmit communication data between the target terminal and the second wireless access point. According to the embodiments of the invention, the anomaly detection and repair is automatically realized. Therefore, a user is prevented from manually checking the mobile terminal of a transfer node. The technical threshold is reduced and the convenience of operation is improved.
