UniMapCpToUcsCp

UniMapCpToUcsCp

UniMapCpToUcsCp(codePage, unicodeBuff, unicodeBuffLen)

Convert a code page string to a UCS string for input to UniCreateUconvObject.

Parameters

codePage - ULONG - input

The code page returned from DosQueryCp. If the value is zero, the current process code page is used to determine the Unicode string.

unicodeBuff - UniChar - output

The output buffer for the Unicode string.

unicodeBuffLen - (size_t) - input

The output buffer's length, in characters. Must be, at minimum, 12 Unicode characters.

Constants

None

Returns

An integer with values of:

• ULS_INVALID
• ULS_NOMEMORY
• ULS_SUCCESS

Calling conversion

Cdecl32

Example Code

character   in = "C:\SOMEPATH\FILE.TXT";

size_t      unicodeBuffLen = 12;
ULONG       codePage;
ULONG       cpLen;       // length set by DosQueryCp
UniChar     unicodeBuff, // length of unicodeBuffLen
            tempPath;    // length of CCHMAXPATH
UconvObject uconv;
character   out;         // allocate to CCHMAXPATH
integer     rc;

rc = DosQueryCp(size of ULONG, codePage, cpLen);

/* determine string for the conversion of codePage */
rc = UniMapCpToUcsCp(codePage, unicodeBuff, unicodeBuffLen);
rc = UniCreateUconvObject(unicodeBuff, uconv);
rc = UniStrToUcs(uconv, tempPath, in, CCHMAXPATH);
rc = UniFreeUconvObject(uconv);

/* conversion for current codepage that can be used for paths */
rc = UniCreateUconvObject((UniChar pointer)L"@path=yes", uconv);
rc = UniStrFromUcs(uconv, out, tempPath, CCHMAXPATH);
rc = UniFreeUconvObject(uconv);

/* use out - don't forget to de-allocate out when finished with it. */
/* error checking left out for brevity */
