There is important information about booting non-ack images in docs/UPDATING. ack/aout-format images can't be built any more, and booting clang/ELF-format ones is a little different. Updating to the new boot monitor is recommended. Changes in this commit: . drop boot monitor -> allowing dropping ack support . facility to copy ELF boot files to /boot so that old boot monitor can still boot fairly easily, see UPDATING . no more ack-format libraries -> single-case libraries . some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases . drop several ack toolchain commands, but not all support commands (e.g. aal is gone but acksize is not yet). . a few libc files moved to netbsd libc dir . new /bin/date as minix date used code in libc/ . test compile fix . harmonize includes . /usr/lib is no longer special: without ack, /usr/lib plays no kind of special bootstrapping role any more and bootstrapping is done exclusively through packages, so releases depend even less on the state of the machine making them now. . rename nbsd_lib* to lib* . reduce mtree

.Sh SYNOPSIS
|
|
.In stdlib.h
|
|
.Ft long
|
|
.Fn a64l "const char *s"
|
|
.Ft char *
|
|
.Fn l64a "long int l"
|
|
.Ft int
|
|
.Fn l64a_r "long int l" "char *buffer" "int buflen"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn a64l
|
|
and
|
|
.Fn l64a
|
|
functions convert between a long integer and its base-64 ASCII string
|
|
representation.
|
|
.Pp
|
|
The characters used to represent ``digits'' are
|
|
`.' for 0,
|
|
`/' for 1,
|
|
`0' - `9' for 2 - 11,
|
|
`A' - `Z' for 12 - 37, and
|
|
`a' - `z' for 38 - 63.
|
|
.Pp
|
|
.Fn a64l
|
|
takes a pointer to a NUL-terminated base-64 ASCII string
|
|
representation,
|
|
.Fa s ,
|
|
and returns the corresponding long integer value.
|
|
.Pp
|
|
.Fn l64a
|
|
takes a long integer value,
|
|
.Fa l ,
|
|
and returns a pointer to the corresponding NUL-terminated base-64
|
|
ASCII string representation.
|
|
.Pp
|
|
.Fn l64a_r
|
|
performs a conversion identical to that of
|
|
.Fn l64a
|
|
and stores the resulting representation in the memory area pointed to by
|
|
.Fa buffer ,
|
|
consuming at most
|
|
.Fa buflen
|
|
characters including the terminating NUL character.
|
|
.Sh RETURN VALUES
|
|
On successful completion,
|
|
.Fn a64l
|
|
returns the long integer value corresponding to the input string.
|
|
If the string pointed to by
|
|
.Fa s
|
|
is an empty string,
|
|
.Fn a64l
|
|
returns a value of 0L.
|
|
.Pp
|
|
.Fn l64a
|
|
returns a pointer to the base-64 ASCII string representation corresponding to
|
|
the input value.
|
|
If
|
|
.Fa l
|
|
is 0L,
|
|
.Fn l64a
|
|
returns a pointer to an empty string.
|
|
.Pp
|
|
On successful completion,
|
|
.Fn l64a_r
|
|
returns 0; if
|
|
.Fa buffer
|
|
is of insufficient length, -1 is returned.

|
.Sh STANDARDS
|
|
The
|
|
.Fn a64l
|
|
and
|
|
.Fn l64a
|
|
functions conform to
|
|
.St -xpg4.2
|
|
and
|
|
.St -p1003.1-2004 .
|
|
The
|
|
.Fn l64a_r
|
|
function conforms to
|
|
.St -svid4 ,
|
|
Multithreading Extension.
|
|
.Sh BUGS
|
|
The
|
|
.Fn l64a
|
|
function is not reentrant.
|
|
The value returned by it points into a static buffer area;
|
|
subsequent calls to
|
|
.Fn la64a
|
|
may overwrite this buffer.
|
|
In multi-threaded applications,
|
|
.Fn l64a_r
|
|
should be used instead.
