函数名称：moyo_parse_number_union - Parse a tomoyo_number_union.*@param: Pointer to "struct tomoyo_acl_param".*@ptr: Pointer to "struct tomoyo_number_union".* Returns true on success, false otherwise.

函数原型：bool tomoyo_parse_number_union(struct tomoyo_acl_param *param, struct tomoyo_number_union *ptr)

返回类型：bool

参数：

类型参数名称
struct tomoyo_acl_param *param
struct tomoyo_number_union *ptr
277  memset(ptr, 0, ptr的长度)
278  如果data[0]恒等于'@'则
279  data自加
280  Maybe NULL. 等于moyo_get_group - Allocate memory for "struct tomoyo_path_group"/"struct tomoyo_number_group".*@param: Pointer to "struct tomoyo_acl_param".*@idx: Index number.* Returns pointer to "struct tomoyo_group" on success, NULL otherwise.
281  返回:Maybe NULL. != NULL
283  data等于moyo_read_token - Read a word from a line.*@param: Pointer to "struct tomoyo_acl_param".* Returns a word on success, "" otherwise.* To allow the caller to skip NULL check, this function returns "" rather than* NULL if there is no more words to read.
284  type等于moyo_parse_ulong - Parse an "unsigned long" value.*@result: Pointer to "unsigned long".*@str: Pointer to string to parse.* Returns one of values in "enum tomoyo_value_type".* The @src is updated to point the first character after the value* on success.
285  如果type恒等于TOMOYO_VALUE_TYPE_INVALID则返回:false
287  values[0]等于v
288  One of values in "enum tomoyo_value_type". [0]等于type
289  如果非data则
290  values[1]等于v
291  One of values in "enum tomoyo_value_type". [1]等于type
292  返回:true
294  如果data自加不等于'-'则返回:false
296  type等于moyo_parse_ulong - Parse an "unsigned long" value.*@result: Pointer to "unsigned long".*@str: Pointer to string to parse.* Returns one of values in "enum tomoyo_value_type".* The @src is updated to point the first character after the value* on success.
297  如果type恒等于TOMOYO_VALUE_TYPE_INVALID或data或values[0]大于v则返回:false
299  values[1]等于v
300  One of values in "enum tomoyo_value_type". [1]等于type
301  返回:true
