VENTI-MEM(3)

💖 VENTI-MEM(3): the bestie manual 💖

okay so this is VENTI-MEM(3) from the Library Functions Manual, and it's literally about error-checking memory allocators 🫶 no cap.

🌸 NAME 🌸

vtbrk, vtmalloc, vtmallocz, vtrealloc, vtstrdup, vtfree — error-checking memory allocators 💅

✨ SYNOPSIS ✨

#include <u.h>
#include <libc.h>
#include <venti.h>

void* vtbrk(int size)

void* vtmalloc(int size)

void* vtmallocz(int size)

void* vtrealloc(void *ptr, int size)

char* vtstrdup(char *s)

void  vtfree(void *ptr)

🦋 DESCRIPTION 🦋

okay so these routines allocate and free memory. on failure, they print an error message and call sysfatal(3). they do not return — like, do not return, periodt 😭💀

vtbrk returns a pointer to a new, permanently allocated block of at least size bytes ✨.

vtmalloc, vtrealloc, and vtstrdup are like malloc, realloc, and strdup, but — as noted above — do not return on error. vtmallocz is like vtmalloc but zeros the block before returning it. memory allocated with all four should be freed with vtfree when no longer needed 💖.
