mem_copy_buffer()

static int mem_copy_buffer ( struct m0_net_buffer *  d_nb, struct m0_net_buffer *  s_nb, m0_bcount_t  num_bytes  )

static

Copy from one buffer to another. Each buffer may have different number of segments and segment sizes. The subroutine does not set the nb_length field of the d_nb buffer.

Parameters

d_nb	The destination buffer pointer.
s_nb	The source buffer pointer.
num_bytes	The number of bytes to copy.

Precondition

mem_buffer_length(d_nb) >= num_bytes && mem_buffer_length(s_nb) >= num_bytes
