- Fix for possible unset uid/gid in toproto
- Fix for default mtree style
- Update libelf
- Importing libexecinfo
- Resynchronize GCC, mpc, gmp, mpfr
- build.sh: Replace params with show-params.
This has been done as the make target has been renamed in the same
way, while a new target named params has been added. This new
target generates a file containing all the parameters, instead of
printing it on the console.
- Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
get getservbyport() out of the inner loop

.Sh SYNOPSIS
|
|
.In gelf.h
|
|
.Ft "GElf_Move *"
|
|
.Fn gelf_getmove "Elf_Data *data" "int ndx" "GElf_Move *move"
|
|
.Ft int
|
|
.Fn gelf_update_move "Elf_Data *data" "int ndx" "GElf_Move *move"
|
|
.Sh DESCRIPTION
|
|
These convenience functions are used to retrieve and update class-dependent
|
|
.Vt Elf32_Move
|
|
and
|
|
.Vt Elf64_Move
|
|
structures in an ELF object.
|
|
.Pp
|
|
Argument
|
|
.Ar data
|
|
is an
|
|
.Vt Elf_Data
|
|
descriptor associated with a section of type
|
|
.Dv SHT_SUNW_move .
|
|
Argument
|
|
.Ar ndx
|
|
is the index of the move record being retrieved or updated.
|
|
The class-independent
|
|
.Vt GElf_Move
|
|
structure is described in
|
|
.Xr gelf 3 .
|
|
.Pp
|
|
Function
|
|
.Fn gelf_getmove
|
|
retrieves class-dependent move record at index
|
|
.Ar ndx
|
|
in data buffer
|
|
.Ar data
|
|
and copies it to the destination pointed to by argument
|
|
.Ar move
|
|
after translation to class-independent form.
|
|
.Pp
|
|
Function
|
|
.Fn gelf_update_move
|
|
converts the class-independent move information pointed to
|
|
by argument
|
|
.Ar move
|
|
to class-dependent form, and writes it to the move record at index
|
|
.Ar ndx
|
|
in the data buffer described by argument
|
|
.Ar data .
|
|
Function
|
|
.Fn gelf_update_move
|
|
signals an error if any of the values in the class-independent
|
|
representation exceeds the representable limits of the target
|
|
type.
|
|
.Sh RETURN VALUES
|
|
Function
|
|
.Fn gelf_getmove
|
|
returns the value of argument
|
|
.Ar move
|
|
if successful, or NULL in case of an error.
|
|
Function
|
|
.Fn gelf_update_move
|
|
returns a non-zero value if successful, or zero in case of an error.
|
|
.Sh ERRORS
|
|
These functions may fail with the following errors:
|
|
.Bl -tag -width "[ELF_E_RESOURCE]"
|
|
.It Bq Er ELF_E_ARGUMENT
|
|
Arguments
|
|
.Ar data
|
|
or
|
|
.Ar move
|
|
were NULL.
|
|
.It Bq Er ELF_E_ARGUMENT
|
|
Argument
|
|
.Ar ndx
|
|
was less than zero or larger than the number of records in the data
|
|
descriptor.
|
|
.It Bq Er ELF_E_ARGUMENT
|
|
Data descriptor
|
|
.Ar data
|
|
was not associated with a section containing move information.
|
|
.It Bq Er ELF_E_RANGE
|
|
