Detailed Description

Generate and return .true. is the input path is an absolute POSIX path (whether existing or virtual), otherwise return .false..

A POSIX path is absolute if,

1. it begins with a POSIX directory separator as stored in DIR_SEP_POSIX_ALL.
   

Parameters

[in]

path

: The input scalar character of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU) containing an existing or virtual path. An empty input path is by definition a relative path (not absolute).

Returns

pathIsAbs : The output scalar logical of default kind LK that is .true. if and only if the input path is an absolute path based on POSIX conventions.

Possible calling interfaces ⛓

use pm_kind, only : LK
use pm_sysPath, only: isPathAbsPosix
logical(LK) :: pathIsAbs
 
pathIsAbs = isPathAbsPosix(path)

Remarks

The procedures under discussion are pure.

The procedures under discussion are elemental.
