CX_SYSTEM_OBJECT::CanonicalizePath

CX_SYSTEM_OBJECT::CanonicalizePath

199720

Description:

The function simplifies a path containing "." or/and "..." (example: CX_ROOTDIR\\\appswh\\\\..) CX_ROOTDIR is replaced by the correct path.

Code example: 
Var(path, cPath)
"CX_ROOTDIR\\" -> path 
path "appswh\\" + -> cPath
cPath <span class="highlight">SystemObject Call(CanonicalizePath)</span> \\ Output: "C:\\classix\\Evaluate\\appswh\\"
"path "appswh\\." + -> cPath
cPath <span class="highlight">SystemObject Call(CanonicalizePath)</span> \\ Output: "C:\\classix\\Evaluate\\appswh"
"path "appswh\\.." + -> cPath
cPath <span class="highlight">SystemObject Call(CanonicalizePath)</span> \\ Output: "C:\\classix\\Evaluate"

"C:\\" -> path 
"path "." + -> cPath
cPath <span class="highlight">SystemObject Call(CanonicalizePath)</span> \\ Output: "C:\\"
"path ".." + -> cPath
cPath <span class="highlight">SystemObject Call(CanonicalizePath)</span> \\ Output: "C:\\"

The correct path of CX_ROOTDIR may differ from the one in the code example.
The system does not check whether the entered path exists.
A path constructed with "/" instead of "\" cannot be transformed with this function
