SND_PCM_LIB_ALLOC_VM(9)                      PCM API                      SND_PCM_LIB_ALLOC_VM(9)



NAME
       snd_pcm_lib_alloc_vmalloc_32_buffer - allocate 32-bit-addressable buffer

SYNOPSIS
       int snd_pcm_lib_alloc_vmalloc_32_buffer(struct snd_pcm_substream * substream,
                                               size_t size);

ARGUMENTS
       substream
           the substream to allocate the buffer to

       size
           the requested buffer size, in bytes

DESCRIPTION
       This function works like snd_pcm_lib_alloc_vmalloc_buffer, but uses vmalloc_32, i.e., the
       pages are allocated from 32-bit-addressable memory.

RETURN
       1 if the buffer was changed, 0 if not changed, or a negative error code.
