Functions
rpcmem_init
Initialize the RPCMEM Library.
Only call this function once before using the RPCMEM Library.
This API is mandatory on pre-Lahaina targets IF the client has linked to the rpcmem.a static library. If the client has only linked libadsprpc.so, libcdsprpc.so, or libsdsprpc.so, then the rpcmem_init call is not required on any target and other rpcmem APIs such as rpcmem_alloc can be called directly.
NOTE: This function is not thread safe.
rpcmem_deinit
Deinitialize the RPCMEM Library.
Only call this function once when the RPCMEM Library is no longer required.
This API is mandatory on pre-Lahaina targets IF the client has linked to the rpcmem.a static library. If the client has only linked libadsprpc.so, libcdsprpc.so, or libsdsprpc.so, then the rpcmem_deinit call is not required on any target.
NOTE: This function is not thread safe.
rpcmem_alloc
Allocate a zero-copy buffer for size upto 2 GB with the FastRPC framework.
Default memory attributes, 2 KB rpcmem_alloc(RPCMEM_HEAP_ID_SYSTEM,RPCMEM_DEFAULT_FLAGS,2048);
Or rpcmem_alloc_def(2048);
Heap 22, uncached, 1 KB rpcmem_alloc(22,0,1024);
Or rpcmem_alloc(22,RPCMEM_FLAG_UNCACHED,1024);
Heap 21, cached, 2 KB rpcmem_alloc(21,RPCMEM_FLAG_CACHED,2048);
Or #include<ion.h>
rpcmem_alloc(21,ION_FLAG_CACHED,2048);
Default memory attributes but from heap 18, 4 KB rpcmem_alloc(18,RPCMEM_DEFAULT_FLAGS,4096);
int
Heap ID to use for memory allocation.
uint32_t
ION flags to use for memory allocation.
int
Buffer size to allocate.
rpcmem_alloc2
Allocate a zero-copy buffer with the FastRPC framework.
The usage examples are same as rpcmem_alloc.
int
Heap ID to use for memory allocation.
uint32_t
ION flags to use for memory allocation.
size_t
Buffer size to allocate.
__attribute__
Allocate a buffer with default settings.
Size of the buffer to be allocated.
rpcmem_free
Free a buffer and ignore invalid buffers.
rpcmem_to_fd
Return an associated file descriptor.
void *
Data pointer for an RPCMEM-allocated buffer.
