GetRoleTextA function (oleacc.h)

Retrieves the localized string that describes the object's role for the specified role value.

Syntax

UINT GetRoleTextA(
  [in]  DWORD lRole,
  [out] LPSTR lpszRole,
  [in]  UINT  cchRoleMax
);

Parameters

[in] lRole

Type: DWORD

One of the object role constants.

[out] lpszRole

Type: LPTSTR

Address of a buffer that receives the role text string. If this parameter is NULL, the function returns the role string's length, not including the null character.

[in] cchRoleMax

Type: UINT

The size of the buffer that is pointed to by the lpszRole parameter. For ANSI strings, this value is measured in bytes; for Unicode strings, it is measured in characters.

Return value

Type: UINT

If successful, and if lpszRole is non-NULL, the return value is the number of bytes (ANSI strings) or characters (Unicode strings) copied into the buffer, not including the terminating null character. If lpszRole is NULL, the return value represents the string's length, not including the null character.

If the string resource does not exist, or if the lpszRole parameter is not a valid pointer, the return value is zero (0). To get extended error information, call GetLastError.

Remarks

Note

The oleacc.h header defines GetRoleText as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
