snd_pcm_lib_alloc_vmalloc_32_buffer (9)

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

substream

the substream to allocate the buffer to

size

the requested buffer size, in bytes

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.

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