what is mutex?

Answer Posted / sunildummati

Short for mutual exclusion object. In computer
programming, a mutex is a program object that allows
multiple program threads to share the same resource, such
as file access, but not simultaneously. When a program is
started, a mutex is created with a unique name. After this
stage, any thread that needs the resource must lock the
mutex from other threads while it is using the resource.
The mutex is set to unlock when the data is no longer
needed or the routine is finished.

(2) When spelled MuTeX, a package of macros for the TeX
typesetting system that supports musical notation. MuTeX
was written by Andrea Steinbach and Angelika Schofer, as a
master's thesis at Rheinische Friedrich-Wilhelms
University.
