mpi_get_buffer

函数名称：mpi_get_buffer() - Returns an allocated buffer with the MPI (msb first).* Caller must free the return string.* This function does return a 0 byte buffer with nbytes set to zero if the* value of A is zero.*@a: a multi precision integer.

函数原型：void *mpi_get_buffer(MPI a, unsigned *nbytes, int *sign)

返回类型：void

参数：

类型	参数	名称
MPI	a
unsigned *	nbytes
int *	sign

209

如果非nbytes则返回:NULL

212

n等于需要存储的数量极大值

214

如果非n则n自加

217

buf等于kmalloc(n, GFP_KERNEL)

219

如果非buf则返回:NULL

222

ret等于mpi_read_buffer() - read MPI to a bufer provided by user (msb first)*@a: a multi precision integer*@buf: bufer to which the output will be written to

224

如果ret则

225

kfree(buf)

226

返回:NULL

228

返回:buf
