- 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 libelf.h
|
|
.Ft "unsigned long"
|
|
.Fn elf_hash "const char *name"
|
|
.Sh DESCRIPTION
|
|
Function
|
|
.Fn elf_hash
|
|
computes a portable hash value for the null terminated string
|
|
pointed to by argument
|
|
.Ar name .
|
|
.Pp
|
|
The hash value returned is will be identical across
|
|
machines of different architectures.
|
|
This allows hash tables to be built on one machine and
|
|
correctly used on another of a different architecture.
|
|
The hash value returned is also guaranteed
|
|
.Em not
|
|
to be the bit pattern of all ones (~0UL).
|
|
.Sh IMPLEMENTATION NOTES
|
|
The library internally uses unsigned 32 bit arithmetic to compute
|
|
the hash value.
