+
+.SH NAME
+elf_scnshndx \- Find the index of the SHT_SYMTAB_SHNDX section associated with
a symbol table
+
+.SH SYNOPSIS
+.nf
+#include <libelf.h>
+
+.BI "int elf_scnshndx(Elf_Scn *" scn ");"
+.fi
+
+.SH DESCRIPTION
+The
+.BR elf_scnshndx ()
+function searches for the
+.BR SHT_SYMTAB_SHNDX
+section associated with a given symbol table section. It returns the section
+index of the corresponding
+.BR SHT_SYMTAB_SHNDX
+section, or zero if none is found.
+
+This function is used for retrieving extended section indices in ELF files
+with many sections, where standard symbol table entries cannot store all
+possible section references directly.
+
+The function only returns a valid result if
+.IR scn
+refers to a section of type
+.BR SHT_SYMTAB .
+Otherwise, the function returns 0.
+
+.SH PARAMETERS
+.TP
+.I scn
+An
+.B Elf_Scn
+pointer referencing a symbol table section.
+
+.SH RETURN VALUE
+Returns the section index of the
+.BR SHT_SYMTAB_SHNDX
+section if found. If no such section is found, returns 0. On error, returns
\-1.
+
+.SH SEE ALSO
+.BR libelf (3),
+.BR elf (5)

+
+.SH HISTORY

+first appeared in elfutils 0.132. This function is a elfutils libelf
extension and
+may not be available in other libelf implementations.
