Overview
The AddPaths function will combine two paths together and produce a string containing a resultant path.
Syntax/Parameters
Syntax
string = AddPaths ( string base, string target );
Parameters
base
A string containing a base path. The path does not require a trailing slash. base should generally be qualified but it is not required.
target
A string containing an unqualified target path. It cannot contain a root position but may contain one or more leading ‘../’ to perform up branch traversing.
Return Value
Returns a string containing the combined paths or an empty string on failure. Use the GetLastError function to retrieve error information.
Remarks
The AddPaths function takes two input paths and combines them to produce a resultant path. The second path (target) must be relative to the first (base) (i.e., within the same logical volume). The AddPaths function also performs path connector logic to properly resolve ‘..’ connectors to traverse up the path tree. The paths can be Windows or URI style. If they are URI and contain a scheme, the QualifyURL function must be used.
In the event of an error, the GetLastError function may return the following values (OR’ed with ERROR_SOFT):
| AP_SOURCE_NOT_RELATIVE | 0x00010000 | Target is not relative path | |
| AP_SOURCE_SYNTAX | 0x00020000 | Syntax error relative path | |
| AP_SOURCE_EXCEEDS_ROOT | 0x00030000 | Up tree '..' went past root | |
| AP_OVERFLOW | 0x00040000 | Result is too large (maximum 512 characters) |
Note that in this situation:
AddPaths("C:\\test\\data\\", "\\data1.txt");
the AddPaths function will return an empty string even though the path operation is technically correct.
The AddPaths function does not check for the validity of the resultant path.
