I have been trying to get the OS version using uts but for some reason I cant seem to obtain it, instead I am getting the output: !!!Hello World!!! Sysname: CYGWIN_NT-10.0-18363 Nodename: LAPTOP-K1QSQFS4 Release: 3.3.6-341.x86_64 Version: 2022-09-05 11:15 UTC Machine: x86_64 done when I want it to output my Host OS windows 10

CodePudding user response：

You're using Cygwin. If you look at the relevant part of the source of its uname() function, you see:

/* Cygwin "version" aka build date */
strcpy (name->version, cygwin_version.dll_build_date);

So getting a date for the version is perfectly normal, intended behavior in the cygwin environment.
