Function Documentation

ngcppClose()

int ngcppClose	(	ngcpp_dma_t *	dev,
		int	term,
		char *	erms )

Close the DMA device. If term is 1, all outstanding DMA transfers are terminated.

ngcppFree()

void ngcppFree

(

void *

ptr

)

Free memory.

ngcppMalloc()

void * ngcppMalloc

(

size_t

size

)

Allocate size bytes of memory.

ngcppMalloc2()

void * ngcppMalloc2	(	void *	ptr,
		size_t	size )

Re(-allocate) size bytes of memory.

ngcppOpen()

int ngcppOpen	(	ngcpp_dma_t *	dev,
		char *	erms )

Open the DMA device.

ngcppReAlloc()

int ngcppReAlloc	(	size_t	bufsize,
		int	n,
		char *	erms )

Reallocate n input ringbuffers of size bufsize. If n is zero the number ringbuffers is determined dynamically according to bufsize and ngcppMIN_RINGBUFSIZE.
