Detailed Description

This is the kernel_type class for generating objects with logical components to determine the operating system (OS) kernel and its name.

When an object of this type is generated, a single object component name corresponding to OS name is filled with,

1. "Windows" if the OS is Windows.
2. "Cygwin" if the OS is Cygwin.
3. "MinGW" if the OS is MinGW.
4. "MSYS" if the OS is MinGW.
5. "Linux" if the OS is Linux.
6. "Darwin" if the OS is Darwin.
7. "FreeBSD" if the OS is FreeBSD.

Otherwise, if the appropriate preprocessing macro is undefined, the type constructor will use the facilities of the runtime shell to infer the Operating System kernel name through either:

1. the Windows OS environmental variable in Windows-style runtime shells.
2. the UNIX OSTYPE environmental variable in UNIX-style runtime shells.
3. the UNIX uname command on unix-style runtime shells.

Warning

The environments "msys", "MinGW", "Cygwin" are not really standalone Operating System kernels, rather Linux compatibility environments within Windows platforms.
As such, when such environments are detected, the windows component of the is component of the object of type kernel_type is always set to .true..

Even though Cygwin and MinGW are considered operating systems independently of Windows

Parameters

[out]	failed	: The output scalar logical of default kind LK that is .true. if and only if an error occurs while inferring the operating system kernel. (optional. If missing and a runtime error occurs, the program will halt by calling error stop.)
[in,out]	errmsg	: The input/output scalar character of default kind SK of arbitrary length type parameter. If an error occurs, errmsg will be set to a descriptive message about the nature of the runtime error. A length of LEN_IOMSG characters is likely sufficient to capture most error messages in full. (optional. It can be present only if failed is also present. If missing, no error message will be output.)

Returns

kernel : The output scalar object of type kernel_type containing the specifics of the operating system kernel name.

Possible calling interfaces ⛓

use pm_kind, only: LK
use pm_sysInfo, only: kernel_type
character(255, SK) :: errmsg
type(kernel_type) :: kernel
logical(LK) :: failed
 
kernel = kernel_type()
kernel = kernel_type(failed)
kernel = kernel_type(failed, errmsg)
