Most Linux machines come with a console command called mtrace, that converts the computer readable format into human-readable text as shown below. If you do not have access to this console command, there is a Perl script, of the same name, that can be downloaded to accomplish the same task.
This is a list of POSIX (Portable Operating System Interface) commands as specified by IEEE Std 1003.1-2024, which is part of the Single UNIX Specification (SUS). These commands can be found on Unix operating systems and most Unix-like operating systems.
The brk and sbrk calls dynamically change the amount of space allocated for the heap segment of the calling process. The change is made by resetting the program break of the process, which determines the maximum space that can be allocated.
mimalloc (pronounced "me-malloc") is a free and open-source compact general-purpose memory allocator developed by Microsoft [2] with focus on performance characteristics. The library is about 11000 lines of code and works as a drop-in replacement for malloc of the C standard library [3] and requires no additional code changes.

The C programming language manages memory statically, automatically, or dynamically.Static-duration variables are allocated in main memory, usually along with the executable code of the program, and persist for the lifetime of the program; automatic-duration variables are allocated on the stack and come and go as functions are called and return.
The Linux kernel also uses the buddy system, with further modifications to minimise external fragmentation, along with various other allocators to manage the memory within blocks. [3] jemalloc [4] is a modern memory allocator that employs, among others, the buddy technique.
