Function Documentation

GM_ENTRY_POINT void gm_dma_free (  gm_port_t *  p, void *  addr )

gm_dma_free() frees p, which was allocated by a call to gm_dma_calloc() or gm_dma_malloc(). Note that the memory is not necessarily unlocked and returned to the operating system, but may be reused in future calls to gm_dma_calloc() or gm_dma_malloc(). Parameters: p  (IN) The GM port. addr  (IN) The address of the memory to be freed. See also: gm_dma_calloc gm_dma_malloc Author: Glenn Brown Version: GM_API_VERSION (as defined in gm.h)

GM_ENTRY_POINT void* gm_dma_malloc (  struct gm_port *  p, gm_size_t  length )

gm_dma_malloc() allocates length bytes of DMAable memory aligned on a 4-byte boundary. Memory should be freed using gm_dma_free(). Parameters: p  (IN) Handle to the GM port. length  (IN) The number of bytes to be malloc'ed. See also: gm_dma_calloc gm_dma_free Author: Glenn Brown Version: GM_API_VERSION (as defined in gm.h)
