Macros | |

Macro Definition Documentation
◆ mrpt_alloca
| #define mrpt_alloca | ( | nBytes | ) | ::malloc(nBytes) |
In platforms and compilers with support to "alloca", allocate a memory block on the stack; if alloca is not supported, it is emulated as a normal "malloc".
- NOTICE: Since in some platforms alloca will be emulated with malloc, alloca_free MUST BE ALWAYS CALLED to avoid memory leaks. This method MUST BE a macro rather than a function in order to operate on the caller's stack.

◆ mrpt_alloca_free
| #define mrpt_alloca_free | ( | mem_block | ) | free(mem_block) |
This method must be called to "free" each memory block allocated with "system::alloca": If the block was really allocated in the stack, no operation is actually performed, otherwise it will be freed from the heap.
This method MUST BE a macro rather than a function in order to operate on the caller's stack.
