Detailed Description

Generate and return .true. if the attempt to set the current working directory to the input dir fails, otherwise return .false. upon success.

The name of this interface is intentionally chosen to be different from chdir which is an Intel ifport and GNU Fortran extension procedure name.

Parameters

[in]

dir

: The input scalar character of default kind SK containing the directory path to which the current working directory should switch.

Returns

failed : The output scalar logical of default kind LK.
It is .true. if and only if an error occurs while setting the current working directory to the specified input dir.

Possible calling interfaces ⛓

use pm_sysPath, only: isFailedChangeDir
use pm_kind, only: LK
logical(LK) :: failed
 
failed = isFailedChangeDir(dir)

Remarks

The procedures under discussion are impure.

Example usage ⛓

program example
 
    use pm_kind, only: LK, IK, SK
    use pm_io, only: display_type
    use pm_sysPath, only: isFailedChangeDir, getDirCurrent, getDirSep
 
    implicit none
 
    character(:, SK), allocatable   :: cpath, npath
    logical(LK)                     :: failed
 
    type(display_type) :: disp
    disp = display_type(file = "main.out.F90")
 
    call disp%skip()
    call disp%show("cpath = getDirCurrent() ! get the current working directory.")
                    cpath = getDirCurrent()
    call disp%show("cpath")
    call disp%show( cpath , deliml = SK_"""" )
    call disp%skip()
    call disp%show("npath = cpath//getDirSep()//SK_'..' ! new working directory.")
                    npath = cpath//getDirSep()//SK_'..'
    call disp%show("npath")
    call disp%show( npath , deliml = SK_"""" )
    call disp%skip()
    call disp%show("isFailedChangeDir(npath)")
    call disp%show( isFailedChangeDir(npath) )
    call disp%skip()
    call disp%show("getDirCurrent()")
    call disp%show( getDirCurrent() , deliml = SK_"""" )
    call disp%skip()

Example Unix compile command via Intel ifort compiler ⛓

#!/usr/bin/env sh
rm main.exe
ifort -fpp -standard-semantics -O3 -Wl,-rpath,../../../lib -I../../../inc main.F90 ../../../lib/libparamonte* -o main.exe
./main.exe

Example Windows Batch compile command via Intel ifort compiler ⛓

del main.exe
set PATH=..\..\..\lib;%PATH%
ifort /fpp /standard-semantics /O3 /I:..\..\..\include main.F90 ..\..\..\lib\libparamonte*.lib /exe:main.exe
main.exe

Example Unix / MinGW compile command via GNU gfortran compiler ⛓

#!/usr/bin/env sh
rm main.exe
gfortran -cpp -ffree-line-length-none -O3 -Wl,-rpath,../../../lib -I../../../inc main.F90 ../../../lib/libparamonte* -o main.exe
./main.exe

Example output ⛓

 
cpath = getDirCurrent() ! get the current working directory.
cpath

npath = cpath//getDirSep()//SK_'..' ! new working directory.

Test:

test_pm_sysPath

Todo:

Low Priority: A subroutine version of this functional interface could be implemented in future to avoid allocations and allow for non-default character kinds.
