函数名称：moyo_argv - Check argv[] in "struct linux_binbrm".*@index: Index number of @arg_ptr.*@arg_ptr: Contents of argv[@index].*@argc: Length of @argv.*@argv: Pointer to "struct tomoyo_argv".*@checked: Set to true if @argv[@index] was found.

函数原型：static bool tomoyo_argv(const unsigned int index, const char *arg_ptr, const int argc, const struct tomoyo_argv *argv, u8 *checked)

返回类型：bool

参数：

类型参数名称
const unsigned intindex
const char *arg_ptr
const intargc
const struct tomoyo_argv *argv
u8 *checked
32  name等于arg_ptr
33  以i小于argc循环
36  如果index不等于index则继续下一循环
38  checked等于1
39  tomoyo_fill_path_info( & arg)
40  result等于moyo_path_matches_pattern - Check whether the given filename matches the given pattern.*@filename: The filename to check.*@pattern: The pattern to compare.* Returns true if matches, false otherwise.* The following patterns are available.* \\ \ itself.
41  如果is_not则result等于非result
43  如果非result则返回:false
46  返回:true
