CTrace Trace File

A TRC file may also be a trace file created by CTrace, a trace and debug library included in some C applications. It contains a record of the low-level processes a program performed during a specific runtime. Developers use TRC files to debug programs.

CTrace is a code library that developers can use to add a trace and debug utility to their C applications. The utility records the low-level processes a program performs, as well as those processes' outputs. Developers can save these records to text files, which are sometimes saved with the .trc file extension. (More commonly, however, CTrace trace files are saved with the .TXT extension.)

If a program that uses the CTrace utility encounters an error, the program's developer can create a TRC file that documents the runtime in which that error occurred. They can then review the file's text and attempt to determine the error's cause. This allows developers to find and fix bugs that would otherwise continue to negatively impact their programs.

NOTE: CTrace is intended for use in multi-threaded applications, but can also be included in single-threaded applications.

How to open a TRC file

TRC files are plain text files, so you can open them and view the trace data they contain in any text editor. Some common text editors include Microsoft Notepad (Windows), Apple TextEdit (Mac), and GitHub Atom (cross-platform).
