Being in a shared library makes no difference, except the application should not use the same signal and nor should any other libraries it loads.

Hi Experts,<br />

I am working on a shared library to provide some functionality. &nbsp;I want to be able to set some attributes when this library is loaded and running in a process. &nbsp;For example, I want to set the log level of my library based on some signals. &nbsp;For example, &nbsp;when the user wants to change the log level, he can change some attributes and notify the process somehow. &nbsp;How can I detect this signal. &nbsp;I am working on Linux.

Hi Experts,

I am working on a shared library to provide some functionality.  I want to be able to set some attributes when this library is loaded and running in a process.  For example, I want to set the log level of my library based on some signals.  For example,  when the user wants to change the log level, he can change some attributes and notify the process somehow.  How can I detect this signal.  I am working on Linux.

sending signal and handling in a shared library

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.
