| .SH DESCRIPTION |
| These routines allocate and free memory. |
| On failure, they print an error message and call |
| .IR sysfatal (3). |
| They do not return. |
| .PP |
| .I Vtbrk |
| returns a pointer to a new, permanently allocated block of at least |
| .I size |
| bytes. |
| .PP |
| .IR Vtmalloc , |
| .IR vtrealloc , |
| and |
| .I vtstrdup |
| are like |
| .IR malloc , |
| .IR realloc , |
| and |
| .IR strdup , |
| but, as noted above, do not return on error. |
| .I Vtmallocz |
| is like |
| .I vtmalloc |
| but zeros the block before returning it. |
| Memory allocated with all four should be freed with |
| .I vtfree |
| when no longer needed. |
