Replaces sbrk() with mmap() for Enhanced Efficiency 🚀
This C library provides a custom memory manager that implements malloc(), realloc(), free(), and calloc() functions, leveraging mmap() for superior performance compared to the traditional sbrk() approach.
✨ Speed Boost: mmap() enables memory allocation in larger chunks, reducing system calls and fragmentation, leading to faster memory allocation and deallocation.
📈 Efficient Memory Management: Provides a controlled environment for memory usage, optimizing performance for your applications.
🔄 Coalesce Free Blocks: The library includes a feature to coalesce adjacent free memory blocks, reducing fragmentation and improving memory reuse efficiency.
📊 Memory Allocation Statistics: Track and print memory allocation statistics, including total memory allocated, total memory freed, current memory usage, and allocation count.
malloc() Allocates a block of memory of the specified size and returns a pointer to the beginning of the block.
free() Frees a previously allocated block of memory, making it available for future allocations.
calloc() Allocates memory for an array of elements, initializes all bytes to zero, and returns a pointer to the allocated space.
realloc() Changes the size of a previously allocated memory block, copying the existing content to the new block.
coalesce_free_blocks() Coalesces adjacent free memory blocks to reduce fragmentation and enhance memory reuse efficiency.
print_memory_statistics() Prints detailed memory allocation statistics:
- Total Allocated: Total bytes allocated.
- Total Freed: Total bytes freed.
- Current Usage: Current bytes in use.
- Allocation Count: Number of allocation operations performed.
#include "myMem.h"
int main() {
void *p1 = malloc(100);
void *p2 = malloc(200);
print_memory_statistics(); // Print statistics after allocations
free(p1);
free(p2);
print_memory_statistics(); // Print statistics after frees
return 0;
}Installation To use this custom memory manager in your project, include the header file and link the implementation file.
