Efence is a software program that halts a program at the specific instruction that overruns or underruns a malloc memory buffer. It helps prevent buffer overflow errors.
When it comes to detecting overruns or underruns in malloc() memory buffers, Electric Fence (efence) is unparalleled. It works by creating a red-zone at the border of each buffer using virtual-memory hardware. As soon as a user touches the red-zone, the program stops, pinpointing the exact instruction that caused the bug. This action triggers GDB to display the source-code line responsible for the error, enabling a fast and precise bug-fixing process.
Electric Fence (efence) is a powerful tool that catches even the previously impossible-to-detect overrun bugs that have been plaguing developers for years. Its innovative approach and support for multiple programming languages make it an essential addition to your software development toolkit.
