Allocating and Freeing Memory /

OTAllocMem

Allocates memory from the Open Transport memory pool.

C INTERFACE

void* OTAllocMem(size_t nbytes)

C++ INTERFACE

None. C++ applications use the C interface to this function.

PARAMETERS

nbytes

The amount (in bytes) of memory to allocate.

DISCUSSION

The OTAllocMem function allocates raw memory from a pool that Open Transport creates for your application. This function returns a pointer to the allocated memory; pass the same pointer to the OTFreeMem function to deallocate this memory.

SPECIAL CONSIDERATIONS

You can call this routine at both hardware interrupt level and from a deferred task. You need to call the OTEnterInterrupt function before you make this call from a hardware interrupt.
