Manage memory
A C user-defined routine (UDR) has access to shared memory for dynamic allocations and stack memory for routine arguments (including the MI_FPARAM structure), local stack variables, and return values.
The DataBlade® API provides functions to manage these types of memory.
| Memory-allocation task | Allocation | Deallocation | Other |
|---|---|---|---|
| Shared memory for user memory | mi_alloc(), mi_dalloc(), mi_realloc(), mi_zalloc() | mi_free() | mi_switch_mem_duration() |
| Shared memory for named memory | mi_named_alloc(), mi_named_zalloc() | mi_named_free() | mi_named_get(), mi_lock_memory(), mi_try_lock_memory(), mi_unlock_memory() |
| Stack memory for routine arguments | mi_call() | None | None |
