Detailed Description

Generate and return the index of the last character of the hostname part of the input UNC path.

The Universal Naming Convention (UNC) is a standard for identifying servers, printers and other resources in a network.
According to the US patent 5341499 (by IBM), the UNC was jointly invented by IBM and Microsoft for use in their jointly developed Local Area Network (LAN) software products.
A UNC path uses double slashes or backslashes to precede the name of the computer.
The host-name portion of a UNC path can consist of either a network name string set by an administrator and maintained by a network naming service like DNS or WINS, or by an IP address.
These hostnames normally refer to either a PC, printer, or other devices.
The path (disk and directories) within the computer are separated with a single slash or backslash, as usual.
Note that in under Microsoft DOS/Windows platforms, drive letters (c:, d:, etc.) are not used in UNC names and if used, the : character is dropped.
The typical structure of a UNC path is the following,
1. On Windows systems: \\hostname\path or //hostname/path has the hostname \\hostname.
2. On Unix systems: //hostname/path has the hostname //hostname.
Note that UNC path names are not universally recognized on all Unix platforms.
For more information, see the POSIX standard.

Parameters

[in]	path	: The input scalar `character` of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU) of arbitrary length type parameter containing the potentially UNC path whose hostname portion is to be identified and the index of its last character returned.
[in]	dirsep	: The input scalar `character` of the same kind as `path`, of arbitrary length type parameter containing the directory separators that might be present in the input `path`. For example, On Windows platforms, this can be DIR_SEP_WINDOWS_ALL. On Unix platforms, this can be DIR_SEP_POSIX_ALL.

Returns: index : The output scalar integer of default kind IK containing the index of the last character of hostname portion of the input UNC path.
If there is no hostname, index = 0 on output.

pm_sysPath
This module contains classes and procedures for manipulating system file/folder paths.
Definition: pm_sysPath.F90:274

Warning: Note that no trimming of the input path is performed by the procedure.
Consequently, any leading or trailing whitespace characters will be significant.
Similarly, single and double quotation marks that appear anywhere in path are significant and kept.

Remarks: The procedures under discussion are pure.; The procedures under discussion are elemental.
