Sh NAME
Nm elf_hash
Nd compute a hash value for a string
Sh LIBRARY
Lb libelf
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
Fa 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.
