总结一处笔误

int link_admin_pwd(char * admin_pwd, char *admin, char*pwd)
{
	if (admin == (char *)NULL ||
		pwd == (char *) NULL)
	{
		return -1;
	}
	if (strlen(admin) == 0 || strlen(pwd) == 0)
	{
		return -2;
	}
	fprintf(admin_pwd, "%s:%s", admin,pwd);
	return 0;
}

CPP:

error C2664: ‘fprintf‘ : cannot convert parameter 1 from ‘char *‘ to ‘FILE *‘

C:

warning C4133: ‘function‘ : incompatible types - from ‘char *‘ to ‘FILE *‘

一出笔误， 用C编译，仅仅报警告，运行起来直接崩溃，

用CPP编译报ERROR，无法继续运行

用C编译不可忽略警告信息啊
