- .SH DESCRIPTION
- These routines allocate and free memory.
- On failure, they print an error message and call
- .IR sysfatal (2).
- 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.
