Module Name:

EmulateGetProfileString.cpp
|
||
|
|
|
||
|
|
Abstract:
|
||
|
|
|
||
|
|
GetPrivateProfileString no longer stops parsing at a space or tab
|
||
|
|
character. When users leave what used to be comments on the tail of the
|
||
|
|
string the comments are now passed to the app resulting in errors.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
This is a general purpose shim
