What is posix standart in C?

[thuongtruong1009]

In C programming, POSIX refers to the set of standard libraries defined by the POSIX standard that provide system interfaces for C programs. These libraries are used to write portable programs that can be run on any POSIX-compliant operating system.

Some of the key POSIX libraries in C include:

• <unistd.h>: Provides access to POSIX system calls related to file I/O, process management, and system configuration.

• <pthread.h>: Provides POSIX threads (also known as pthreads) for multi-threaded programming.

• <signal.h>: Provides POSIX signals for handling asynchronous events and interrupt handling.

• <time.h>: Provides functions for working with dates and times.

• <fcntl.h>: Provides POSIX file control options for working with file descriptors.

• <sys/socket.h>: Provides POSIX sockets for network programming.

The POSIX standard libraries provide a consistent interface for C programs to access system services, making it easier to write portable code that can be run on different operating systems.
