Detailed Description

Generate and return a path quoted with double quotation marks where all instances of double quotes \(\ms{"}\) within the path are removed.

This procedure exists to minimize security vulnerabilities associated with paths that may contain harmful system commands.
To ensure paths are interpreted as simple strings, they must be quoted with proper quotation marks on both Windows and Unix-like platforms.
The path returned by this procedure is as close as one can get to a verbatim path in Windows CMD.
Windows-style paths cannot contain double quotation marks. However, their dangling presence can create security vulnerabilities.
As such, if a path is be used in a call to a CMD runtime shell, it is recommended to pass it to this procedure to ensure the path is quoted and all instances of dangling quotation marks \(\ms{"}\) are gracefully escaped.
See also the warnings below.

When should I quote a Windows CMD path using this generic interface?
Quoting CMD paths is crucial for graceful handling of situations where,

1. the path is too long (> 255 characters), or
2. the path contains blanks or dangling double-quotation marks, or
3. the path mixes forward slash and backward slash as directory separators.
   

Parameters

[in]

path

: The input scalar character of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU) containing the path to be enclosed with quotation marks.

Returns

pathVerbatim : The output allocatable scalar of type character of the same kind as path containing the modified input path enclosed with double quotation marks where all instances of double quotation marks within the path are removed.

Possible calling interfaces ⛓

use pm_sysPath, only: getPathVerbatimCMD
 
pathVerbatim = getPathVerbatimCMD(path)

Warning

Note that this procedure does not inspect the input path for the presence of other illegal Windows reserved characters (e.g., WINDOWS_RESERVED_STR).
The presence of illegal characters in a Windows path can lead to runtime errors even if the path is quoted by the procedures of this generic interface.

The Windows CMD wildcard characters remain interpretable by the CMD shell if any are present in the input path.
The asterisk * and question mark ? are used as wildcard characters in Windows CMD, as they are in MS-DOS and Windows.
The asterisk matches any sequence of characters, whereas the question mark matches any single character.

The pure procedure(s) documented herein become impure when the ParaMonte library is compiled with preprocessor macro CHECK_ENABLED=1.
By default, these procedures are pure in release build and impure in debug and testing builds. The impurity is caused by the call to procedures whose purity depends on the library build configuration.
