無法使LibXL xlSheetGetNamedRange正常工作

Question

我正在嘗試使用LibXL。我可以從工作表中提取數據，但需要一個函數來將具有Excel行和列索引的字符串轉換爲startRow，endRow，startCol，endCol，即

將「A1：B3」轉換爲startRow = 0，endRow = 2，startCol = 0，endCol = 1（LibXL使用基於0的索引）

我試過了我能想到的所有東西。該庫沒有附帶任何使用該功能的示例，而且文檔相當稀少。我究竟做錯了什麼？

這裏是我的代碼：

int main() 
{ 
    const char range[] = "B2:C3"; 
    int i, ret, rowFirst=0, rowLast=0, colFirst=0, colLast=0; 
    BookHandle book; 
    SheetHandle sheet; 

    book = xlCreateBook(); 

    ret = xlBookLoad(book, "/home/jason/Downloads/panel.xls"); 

    sheet = xlBookGetSheet(book, 0); 

    ret = xlSheetGetNamedRange(sheet, &range[0], &rowFirst, &rowLast, &colFirst, &colLast); 

    printf("ret from xlSheet...Range = %d\n", ret); 

    printf("%s\n", xlBookErrorMessage(book)); 
    printf("rowLast = %d\n", rowLast); 
    printf("rowLast = %d\n", rowLast); 
    printf("colFirst = %d\n", colFirst); 
    printf("colLast = %d\n", colLast); 

    return 0; 

}

使用xlSheetAddrToRowCol（）函數用於此目的：

int rowStart, colStart, rowEnd, colEnd; 
int rowRelativeStart, colRelativeStart, rowRelativeEnd, colRelativeEnd; 

xlSheetAddrToRowCol(sheet, "B2", &rowStart, &colStart, &rowRelativeStart, &colRelativeStart); 
xlSheetAddrToRowCol(sheet, "C3", &rowEnd, &colEnd, &rowRelativeEnd, &colRelativeEnd);
