NAME

       snd_dma_alloc_pages - allocate the buffer area according to the given type

SYNOPSIS

       int snd_dma_alloc_pages(int type, struct device * device, size_t size, struct snd_dma_buffer * dmab);

ARGUMENTS

       type
	   the DMA buffer type

       device
	   the device pointer

       size
	   the buffer size to allocate

       dmab
	   buffer allocation record to store the allocated data

DESCRIPTION

       Calls the memory-allocator function for the corresponding buffer type.

RETURN

       Zero if the buffer with the given size is allocated successfully, otherwise a negative value on error.

NAME

       cpg_zcb_alloc - Allocates a zero copy buffer #include <corosync/cpg.h>

       int cpg_zcb_alloc(cpg_handle_t handle, size_t size, void **buffer);

DESCRIPTION

       The  cpg_zcb_alloc  function  will allocate a zero copy buffer for use with the cpg_zcb_mcast_joined(3) funtion.  This buffer should not be
       used in another thread while a cpg_zcb_mcast_joined operation is taking place on the buffer.  The buffer is allocated via operating  system
       mechanisms to avoid copying in the IPC layer.

       The argument handle describes the handle on which the buffer will be allocated.

       The argument size requests a buffer of size be allocated.

       The buffer argument is set to the buffer address that is allocated by this operatoin.

RETURN VALUE

       This call returns the CPG_OK value if successful, otherwise an error is returned.

ERRORS

       The errors are undocumented.
