VENTI-MEM(2)                  System Calls Manual                 VENTI-MEM(2)



NAME
       vtbrk,  vtmalloc, vtmallocz, vtrealloc, vtstrdup, vtfree - error-check‐
       ing 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
       These routines allocate and free memory.  On  failure,  they  print  an
       error message and call sysfatal (from perror(2)).  They do not return.

       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 vtmal‐
       loc but zeros the block before returning it.  Memory allocated with all
       four should be freed with vtfree when no longer needed.
