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.
