转换的字符数组一个const gchar * [英] converting an array of characters to a const gchar*

问题描述

我有一个字符数组，其中包含一个字符串：

I've got an array of characters which contains a string:

char buf[MAXBUFLEN];
buf[0] = 'f';
buf[1] = 'o';
buf[2] = 'o';
buf[3] = '\0';

我在找这个字符串作为参数传递给 gtk_text_buffer_insert 函数，以将其插入到 GtkTextBuffer 。我想不通的是如何将其转换为一个常量gchar * ，这是 gtk_text_buffer_insert 预计为第三个参数。

I'm looking to pass this string as an argument to the gtk_text_buffer_insert function in order to insert it into a GtkTextBuffer. What I can't figure out is how to convert it to a const gchar *, which is what gtk_text_buffer_insert expects as its third argument.

任何人能帮助我吗？

推荐答案

gchar 就是的typedef 的字符和数组为const指针的转换是隐式的，所以你可以通过它：

gchar is just a typedef for char and the conversion from arrays to const pointers is implicit, so you can just pass it:

someFunctionExpectingConstGcharPointer(buf);

请注意，您也可以直接用字符串初始化数组：

Note that you can also directly initialize arrays with string literals:

char buf[MAXBUFLEN] = "foo";
