UniFreeUconvObject

UniFreeUconvObject(uconvObj): Free the conversion object from memory.

Parameters

uconvObj - UconvObject - input: The conversion object created from UniCreateUconvObject.

Constants

None

Returns

An integer with values of:

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 uconvObj;
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, uconvObj);
rc = UniStrToUcs(uconvObj, tempPath, in, CCHMAXPATH);
rc = UniFreeUconvObject(uconvObj);

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

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