将根据 Array of CHAR 数据类型创建一个包含各个字符的结构。CHARS 结构(“arrayCHARS”)的长度为 10 个字符 (Array ... [0..9])。根据参数 PCHARS(“pointerCHARS”)的值“0”,从该结构的第一个字符开始写入( “0”包含字符串(“s...

character(len=1) :: chararray(42) integer(1) :: int1array(42) The 42, in your code would likely be replaced with a variable (to facillitate returning different object types/sizes) You may want to create a function that returns one of: type(yourObject), ...

在C的标准库中,我们通常使用字符数组(char array)或字符指针(char pointer)来表示和处理字符串。尽管C11标准引入了新的字符串处理函数,并且有其他库(如POSIX)也提供了对字符串操作的增强,但字符串的基础仍然是字符数组。一、字符串的基础 字符数组 在C语言中,字符串可以简单地看作是一个以\0(空字符,...
一般对于char* ,void*这种可以直接对应IntPtr,比如在C#中,我们经常用string类型,其转换为IntPtr再传给char*,void*等 例如char*与string互转 string a = "11"; char* aChar = (char*)System.Runtime.InteropServices.Marshal.StringToHGlobalAnsi(a).ToPointer(); ...
