什么是Delphi等同物
unsigned char**
C
i m 无法确定其指向一个阵列或指向点人的点,或两者在C中相同。

EDIT In C both pointer to an array and pointer to a pointer have different meaning to the compiler (thanks caf).
在C阵列中,只是记忆的一部分。 没有任何诸如<代码>Length(array)、Low(array)
或High(array)
等功能,可在帕斯卡尔阵列上使用。 为了实际目的,Pascal方案制定者C阵列通常可以运到Pascal点,特别是在向各种APIC发出功能呼吁时。
如果我们假设u signed char
can be translation to byte
in Delphi,那么unsign char *
可翻译成^byte
。 通常通过<条码> 类型条码>声明进行。
type
PByte = ^byte;
PPByte = ^PByte;
两者在C相同。 但是,通常在你看到这一点时,这有一系列的果园。 我宣布:
type
PAnsiCharArray = ^TAnsiCharArray;
TAnsiCharArray = array[0..0] of PAnsiChar;
幸运的是,但后来又是最难以与《刑法》互动的。 但它应当发挥作用。
<><><>> > > 同样的情况。
unsigned char** p1;
unsigned char* p2[N];
unsigned char (*p3)[N];
<代码>p1为未签名焦炭的点子。 它可以指p2
中的一项内容,该要素是一系列与未签署文书有关的要点:p3
是一系列未签署文书的指点。 详细情况见CFAQ。 Edit: 这里有一个较好的例子:。
这是指点人。
仅限<>点/点>。{*}
但是,点索引公约意味着,使用阵列或点码是可行的。 首先,你一般认为是这样的事情。
int main(int argc, char** argv)
这也是将其编入一系列<代码>char*的实例(其分配和结构由本组织管理)。
{*}Because an range and a pointer are not the same matter in c. 相反, a range “decays” to pointer when used in a pointer context.
