我是 C 的新手，我试图用函数的结果填充文件范围的数组变量，这是一个简单的代码示例来说明我的意思，谁能指出我为什么这不起作用的方向？
#include <sys/types.h>
#include <dirent.h>
#include <regex.h>
#include <stdio.h>
#include <gtk/gtk.h>
#include <string.h>
#include <unistd.h>
#include <pwd.h>
static gchar *external_names;
void directories(int arraylength, gchar internal_names[][100]){
int n;
for (n = 0; n < arraylength; n++)
{
strcpy(external_names[n], internal_names[n]);
}
for (n = 0; n < arraylength; n++)
{
printf("%s internal with %s external\n",internal_names[n], external_names[n]);
}
}
void main()
{
gchar anotherarray[10][100];
directories(10, anotherarray);
}
