Memory Allocation ConfigurationΒΆ

Users have the flexibility to customize the memory allocation strategy for Eclipse Cyclone DDS by leveraging their own memory allocation libraries. To utilise your preferred memory allocation functions, follow these steps:

  1. Include dds/ddsrt/heap.h To gain access to ddsrt_allocation_ops_t and ddsrt_set_allocator.

  2. Set the allocation operations Define a ddsrt_allocation_ops_t structure that contains pointers to the functions you want to use for memory allocation and deallocation (malloc, calloc, realloc, and free).

  3. Provide ddsrt the operations Utilize the ddsrt_set_allocator function to set the ops chosen in step 2.

  4. Link with custom library Compile and link your application with the library that contains the functions specified in the ddsrt_allocation_ops_t structure created in step 2.

By following these steps, you can tailor the memory allocation mechanism of Eclipse Cyclone DDS to meet your specific requirements.
