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