EXPORT_C TInt TFindFile::FindByPath(const TDesC& aFileName,const TDesC* aPath)
/**
Searches for a file/directory in one or more directories in the path.

The search ends when the file/directory is found, or when every directory
specified in the path list has been unsuccessfully searched.

Notes:
	
1. For the equivalent search using wildcards, use FindWildByPath().

2. After a file has been found, use TFindFile::File() to get the fully qualified path of the file. To
   search for the next occurrence, use TFindFile::Find().

@param aFileName The filename to search for. If this specifies a directory as well
                 as a filename, then that directory is searched first.
@param aPath     A list of directories to be searched. Paths in this list must
                 be separated by a semicolon character, but a semicolon is not
                 required after the	final path. The directories are searched in
                 the order in which they occur in the list. If a path in
                 the list contains a drive letter, that drive alone is searched.
                 If a path contains no drive letter, the function searches for
                 the file in that directory on every available drive in turn,
                 beginning with drive Y:, in descending alphabetical order
                 and ending with drive Z:.When path is empty then session path 
                 will be used for the search.

@return KErrNone, if the filename was found;
        KErrNotFound, if the filename was not found.
        KErrArgument, if the filename is empty.
