+.B #include <gelf.h>
+
+.BI "int gelf_update_dyn (Elf_Data *" data ", int " ndx ", GElf_Dyn *" src ");"
+
+.SH DESCRIPTION

+.TP
+.I ndx
+Zero\-based index of the dynamic table entry to be updated within
+.IR data .

+.TP
+.I src
+Pointer to a caller\-provided dynamic table entry. For
+.B ELFCLASS32
+binaries,
+.B d_tag
+should be able to fit within a signed 32-bit value
+while
+.B d_val
