Name
__kfifo_put —
puts some data into the FIFO, no locking version
Synopsis
unsigned int __kfifo_put ( | struct kfifo * | fifo, |
| | unsigned char * | buffer, |
| | unsigned int | len); |
Arguments
fifo
the fifo to be used.
buffer
the data to be added.
len
the length of the data to be added.
Description
This function copies at most 'len' bytes from the 'buffer' into
the FIFO depending on the free space, and returns the number of
bytes copied.
Note that with only one concurrent reader and one concurrent
writer, you don't need extra locking to use these functions.
