Detailed Description

Generate and return the path separator character used by the runtime processor shell for separating paths from each other in the PATH environmental variable.

The path separator character returned by this generic interface can be used for splitting the contents of the processor environmental PATH variable to separate directory paths.

1. The path separator for Windows-based terminals such as CMD and PowerShell is PATH_SEP_WINDOWS.
   
2. The path separator for POSIX-compliant terminals such as sh, bash, csh, zsh, ... is PATH_SEP_POSIX.
   

Parameters

[in]	mold	: The input scalar character of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU) of length 1. The value of mold s ignored. However, its kind type parameter is used to to set the kind type parameter of the output dirseps. (optional, default = SK_" " where SK refers to the default character kind SK.) if and only if an error occurs while inferring the system shell directory separator. (optional. If missing and a runtime error occurs, the program will halt by calling error stop.)
[out]	failed	: The output scalar logical of default kind LK that is .true. if and only if an error occurs while the procedure is performing the task. (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 an error occurs, errmsg will be set to a descriptive message about the nature of the runtime error. A length of LEN_IOMSG characters is likely sufficient to capture most error messages in full. (optional. If missing, no error message will be output. Its presence is relevant only if failed is also present.)

Returns

pathsep : The output scalar character of default kind SK of length type parameter of 1 containing the path separator character used by the runtime processor shell for separating paths from each other in the PATH environmental variable.

Possible calling interfaces ⛓

use pm_sysPath, only: getPathSep
character(1, SK) :: pathsep
 
pathsep = getPathSep(failed = failed, errmsg = errmsg)
pathsep = getPathSep(mold, failed = failed, errmsg = errmsg)

Remarks

The procedures under discussion are impure.
