Gets information about an item in a header control. You can use this macro or send the HDM_GETITEM message explicitly.
void Header_GetItem( hwndHD, i, phdi );
A handle to the header control.
The index of the item for which information is to be retrieved.
A pointer to an HDITEM structure. When the message is sent, the mask member indicates the type of information being requested. When the message returns, the other members receive the requested information. If the mask member specifies zero, the message returns TRUE but copies no information to the structure.
If the HDI_TEXT flag is set in the mask member of the HDITEM structure, the control may change the pszText member of the structure to point to the new text instead of filling the buffer with the requested text. Applications should not assume that the text will always be placed in the requested buffer.
The Header_GetItem macro is defined as follows:
#define Header_GetItem(hwndHD, index, phdi) \ (BOOL)SendMessage((hwndHD), HDM_GETITEM, \ (WPARAM)(int)(index), (LPARAM)(LPHDITEM)(phdi))
