我想定义一个这样的路径:
#define PATH /abc/xyz/lmn

该PATH是具有文件foo1,foo2,foo3,... foo115的目录.
如何在"打开"调用中使用此#define打开foo1,foo2,... foo115?
我想基本上使用指令执行此操作:
fd = open("/abc/xyz/lmn/foo1", O_RDONLY);

#define PATH "/abc/xyz/lmn"
int main (int argc, char **argv)
{
char file2open[256];
int i;
for (i = 1; i <= 115; i++)
{
sprintf (file2open, "%sfoo%d", PATH, i);
fd = open (file2open, O_RDONLY)
......
close (fd);
}
}
