Generate and return the absolute path corresponding to the input (potentially relative) path.
The procedures of this generic interface take the following steps to generate the absolute path corresponding to the input path
,
-
If the input
path
is empty, the absolute path to the current directory will be returned.
-
If the input
path
is an absolute path determined via isPathAbsPosix or isPathAbsWindows, the input path
is returned as the output absolute path.
-
If the input
path
is relative, then,
-
If the library is compiled with Intel compilers, the absolute path is determined by a call to
FullPathQQ()
procedure of ifport
module of the Intel ifort
compiler.
-
If the above step fails or if the compiler is non-intel,
-
The absolute path is directly inferred by a system call to the relevant Microsoft or Windows PowerShell command if the shell is available on the platform.
-
If all of the above approaches fail or do not apply (particularly the case with POSIX-compliant runtime shells), the absolute path is constructed by appending the current working directory to the partially qualified input
path
.
See the warnings and remarks below.
- Parameters
-
[in] | path | : The input scalar character of kind SK containing the relative path to be resolved to the corresponding absolute path.
|
[out] | failed | : The output scalar logical of default kind LK.
It is .true. if and only if an error occurs while resolving path .
(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 present and an error occurs, it is assigned an explanatory message describing the nature of the error that has occurred.
A length of 2047 characters for errmsg is likely enough to capture most error messages in full.
(optional. It can be present only if failed is also present.) |
- Returns
pathAbs
: The output allocatable
scalar character
of default kind SK containing the absolute path corresponding to the input (potentially relative) path
.
-
If the input
path
is relative but the path resolution succeeds, the program sets pathAbs
to the resolved path and failed = .false.
upon return.
-
If the input
path
is relative but the path resolution fails, the program sets pathAbs = path
and failed = .true.
upon return.
-
If the input
path
is absolute already, the program sets pathAbs = path
and failed = .false.
upon return.
