MLSetAllocParameter()

void MLSetAllocParameter(char* p, MLAllocator a, MLDeallocator d)
sets the memory allocator and deallocator specified by a and d in the MLParameters object p for later use with MLInitialize().

MORE INFORMATION

Use MLSetAllocParameter() to install special memory allocators in the MathLink library. The library will use the allocators specified by a and d for all dynamic memory allocations.

a and d must have the same call signature as the C memory allocator functions malloc() and free().

a and d must be thread-safe.

MLSetAllocParameter() is declared in the MathLink header file mathlink.h.
