DSP/BIOS MEM_alloc() function

Afaik  the MEM manager keeps a linked list of free blocks for each segment, I don't  know if there is an equivalent list of used blocks.

We use the following code to walk through this list to find the maximum address allocated in a segment.

hope this helps

// getUsedTill evaluates the highest address allocated.
// parameter pUsedTill is updated with the result
// This function looks for the last free memory block in the segment segId and returns
// the start address - 1
void getUsedTill(Int segId, Ptr* pUsedTill)
{
    MEM_Header *pMyHeader = &MEM_freelist[ segId ];
    MEM_Header *allocMem = pMyHeader->next;
    MEM_Header *maxAddr = allocMem;
   
    while( allocMem->next )
   
    {
        allocMem =  allocMem->next;  
        if (allocMem>maxAddr) maxAddr=allocMem; 
    };

    *pUsedTill = (void*) ((unsigned int)maxAddr -1);
}
