函数名称：aa_label_snxprint - print a label name to a string buffer*@str: buffer to write to

函数原型：int aa_label_snxprint(char *str, size_t size, struct aa_ns *ns, struct aa_label *label, int flags)

返回类型：int

参数：

类型参数名称
char *str
size_tsize
struct aa_ns *ns
struct aa_label *label
intflags
1599  struct aa_ns * prev_ns = NULL
1601  count等于0, total等于0
1604  AA_BUG(!str && size != 0)
1605  AA_BUG(!label)
1607  如果flags按位与FLAG_ABS_ROOT则
1608  ns等于 profile namespace
1609  len等于snprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@
1610  helper macro for snprint routines (total, len, size, str)
1611  否则如果非ns则
1612  ns等于labels_ns(label)
1616  如果aa_ns_visible - test if @view is visible from @curr*@curr: namespace to treat as the parent (NOT NULL)*@view: namespace to test if visible from @curr (NOT NULL)*@subns: whether view of a subns is allowed* Returns: true if @view is visible from @curr else 则
1617  如果count大于0则
1621  len等于aa_profile_snxprint - print a profile name to a buffer*@str: buffer to write to
1624  helper macro for snprint routines (total, len, size, str)
1625  count自加
1629  如果count恒等于0则
1630  如果flags按位与FLAG_HIDDEN_UNCONFINED则返回:snprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@
1632  返回:snprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@
1638  如果 any visible label is not unconfined the display_mode returns true 则
1639  len等于snprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@
1641  helper macro for snprint routines (total, len, size, str)
1644  返回:total
