+.TH ELF_NEWDATA 3 2025-06-30 "Libelf" "Libelf Programmer's Manual"
+
+.SH NAME
+elf_newdata \- create a new Elf_Data descriptor for a section
+
+.SH SYNOPSIS
+.nf
+#include <libelf.h>
+
+.BI "Elf_Data * elf_newdata(Elf_Scn *" scn ");"
+.fi
+
+.SH DESCRIPTION
+The
+.BR elf_newdata ()
+function creates a new
+.BR Elf_Data
+descriptor associated with the section referred to by
+.I scn .
+This descriptor can be used to describe new section contents for an ELF object
+being constructed or modified.
+
+The section must not be the null section (index 0), and the section header must
+already be initialized (for example, by calling
+.BR elf_getshdr ()
+after creating the section via
+.BR elf_newscn ()).
+If the section has not yet been assigned data, or was created using
+.BR elf_newscn (),
+this function creates the first
+.BR Elf_Data
+descriptor for the section.
+
+Subsequent calls to
+.BR elf_newdata ()
+will append new data descriptors to the section.
+
+The returned descriptor is marked dirty so that it will be included during
+.BR elf_update () .
+
+.SH PARAMETERS
+.TP
+.I scn
+A section descriptor to which the new data descriptor should be attached.
+Must not be the null section.
+
+.SH RETURN VALUE
+On success, a pointer to a new, writable
+.BR Elf_Data
+descriptor is returned. On failure, NULL is returned.
+
+The caller is responsible for configuring the return value.
