Routine Description:
|
|
|
|
Allocates and returns a pointer to a new string containing a copy of the
|
|
original string in which environment-variables replaced by their defined
|
|
values.
|
|
|
|
Uses the Win-32 API ExpandEnvironmentStrings.
|
|
|
|
The caller must free the returned string using HeapFree(LocalProcessHeap).
|
|
|
|
Arguments:
|
|
|
|
lpOriginalString - Pointer to a null-terminated string that contains
|
|
environment-variable strings of the form: %variableName%. For
|
|
each such reference, the %variableName% portion is replaced
|
|
with the current value of that environment variable.
|
|
|
|
The replacement rules are the same as those used by the command
|
|
interpreter. Case is ignored when looking up the environment-
|
|
variable name. If the name is not found, the %variableName%
|
|
portion is left undisturbed.
|
|
|
|
Return Value:
|
|
|
|
If the function succeeds, the return value is a pointer to the destination
|
|
string containing the result of the expansion. The caller must free
|
|
this memory using HeapFree for the current process heap.
|
|
|
|
If the function fails, the return value is NULL. To get extended error
|
|
information, call GetLastError().

|
|
|
|
Routine Description:
|
|
|
|
Builds the invocation string, as the name suggests. It expands out the
|
|
environment variables in the recovery app path, and adds in
|
|
/sifpath=<path to the sif file> at the end of the command. So for an
|
|
entry in the COMMANDS section of the form:
|
|
4=1,3500,0,"%TEMP%\app.exe","/param1 /param2"
|
|
|
|
the invocation string would be of the form:
|
|
c:\temp\app.exe /param1 /param2 /sifpath=c:\windows\repair\asr.sif
|
|
|
|
Arguments:
|
|
|
|
pNode - The node from which to build the invocation string.
|
|
|
|
lpSifPath - A null terminated UNICODE string containing the full path and
|
|
file-name of the ASR state file to be used for the recovery.
|
|
|
|
This parameter may contain unexpanded environment variables
|
|
between "%" signs (such as %systemroot%\repair\asr.sif),
|
|
|
|
Return Value:
|
|
|
|
If the function succeeds, the return value is a pointer to the destination
|
|
string containing the result of the expansion. The caller must free
|
|
this memory using HeapFree for the current process heap.
|
|
|
|
If the function fails, the return value is NULL. To get extended error
|
|
information, call GetLastError().
