The stdlib_version module

Introduction

The stdlib_version module contains the version of the standard library. The version information can be used as a compile time constant or retrieved from a getter function at runtime. In case the standard library is dynamically linked, the version number retrieved from the getter might mismatch the compile time constants provided from the version built against. Therefore, it is recommended to retrieve the version information always at runtime.

Constants provided by stdlib_version

stdlib_version_string

String constant representing the version number.

stdlib_version_compact

Compact representation of the version string following the scheme: major * 10000 + minor * 100 + patch.

get_stdlib_version

Experimental

Description

Getter function to retrieve version information

Syntax

res = stdlib_version ([major], [minor], [patch], [string])

Pure subroutine.

Argument

major: shall be an intrinsic integer type. It is an optional, intent(out) argument. minor: shall be an intrinsic integer type. It is an optional, intent(out) argument. patch: shall be an intrinsic integer type. It is an optional, intent(out) argument. string: shall be a deferred length character type. It is an optional, intent(out) argument.

Example

program demo_version
use stdlib_version, only : get_stdlib_version
implicit none
character(len=:), allocatable :: version
call get_stdlib_version(string=version)
print '(a)', version
end program demo_version
