[This function is available through Windows XP with Service Pack 2 (SP2) and Windows Server 2003. It might be altered or unavailable in subsequent versions of Windows.]

Copies a string from one buffer to another.

Syntax

int WINAPI Str_GetPtr(
  _In_    LPCTSTR pszSource,
  _Inout_ LPCSTR  pszDest,
  _In_    int     cchDest
);

Parameters

pszSource [in]

Type: LPCTSTR

A pointer to a source string.

pszDest [in, out]

Type: LPCSTR

A pointer to the destination buffer. This value can be NULL.

cchDest [in]

Type: int

The size of pszDest, in characters.

Return value

Type: int

If pszDest is NULL or cchDest is zero, returns the size of the buffer, in characters, needed to contain a null-terminated copy of the string pointed to by pszSource.

If pszDest is non-NULL, returns the number of characters successfully copied, including the terminating null character.

If pszDest cannot hold the entire string pointed to by pszSource, then (cchDest-1) characters are copied, the string null-terminated, and cchDest returned.

Remarks

Str_GetPtr is available as ANSI (Str_GetPtrA) and Unicode (Str_GetPtrW) versions. These functions are not exported by name or declared in a public header file. To use them, you must use GetProcAddress and request ordinal 233 (Str_GetPtrA) or 235 (Str_GetPtrW) from ComCtl32.dll to obtain a function pointer.
