+.TH ELF_HASH 3 2025-03-31 "Libelf" "Libelf Programmer's Manual"
+
+.SH NAME
+elf_hash \- Compute the standard ELF hash of a string.
+
+.SH SYNOPSIS
+.nf
+#include <libelf.h>
+
+.BI "unsigned long int elf_hash(const char *" string ");"
+
+.SH DESCRIPTION
+The
+.B elf_hash
+function computes the standard ELF hash value for a null-terminated
+string.  The hash values are typically used in ELF object files for
+symbol table hashing.  The hash function is used in SHT_HASH sections as
+it avoids generating architecture-dependent values and is suitable for use
+across architectures.
+
+.SH PARAMETERS
+.TP
+.I string
+NULL-terminated string to be hashed.
+
+.SH RETURN VALUE
+This function returns the standard ELF hash value for
+.IR string .
+Only the lower 32 bits of the return value are used.
+
+.SH SEE ALSO
+.BR libelf (3),
+.BR elf (5)
+
+.SH ATTRIBUTES
+For an explanation of the terms used in this section, see
+.BR attributes (7).
