NLS/DBCS-aware string class: GetPrivateProfileString method
|
|
|
|
This file contains the implementation of the GetPrivateProfileString method
|
|
for the NLS_STR class. It is separate so that clients of NLS_STR who
|
|
do not use this operator need not link to it.

NAME: NLS_STR::GetPrivateProfileString
|
|
|
|
SYNOPSIS: Loads a string from an INI file.
|
|
|
|
ENTRY: pszFile - name of INI file to read.
|
|
pszSection - name of section (excluding square brackets).
|
|
pszKey - key name to retrieve.
|
|
pszDefault - default value if key not found.
|
|
|
|
EXIT: String contains the value associated with the key.
|
|
|
|
NOTES: The string is truncated if it's being loaded into an
|
|
owner-alloc string and doesn't entirely fit.
|
|
|
|
No character-set assumptions are made about the string.
|
|
If the character set of the string being loaded is
|
|
different from the ambient set of the NLS_STR, use
|
|
SetOEM() or SetAnsi() to make the NLS_STR correct.
