函数名称:ring_buffer_has_space
函数原型:static __always_inline bool ring_buffer_has_space(unsigned long head, unsigned long tail, unsigned long data_size, unsigned int size, bool backward)
返回类型:bool
参数:
类型 | 参数 | 名称 |
---|---|---|
unsigned long | head | |
unsigned long | tail | |
unsigned long | data_size | |
unsigned int | size | |
bool | backward |
142 | 如果非backward则返回:Return space available, 0..size-1. We always leave one free charas a completely full buffer has head == tail, which is the same asempty. (head, tail, data_size)大于等于size |
144 | 否则返回:Return space available, 0..size-1. We always leave one free charas a completely full buffer has head == tail, which is the same asempty. (tail, head, data_size)大于等于size |
