Can there be a method determining the number of entries in the .dynamic section of an ELF file without using the readelf utility? I am trying to output data from the .dynamic section using the gelf_getdyn() function, but cannot figure out a way of programmatically finding the number of entries in this section. Any help or webpages that can help (cannot find the source code for readelf) would be extremely appreciative.

readelf is part of binutils, look at that for the source. – SoronelHaetir Jan 11 '18 at 20:06

You simply iterate over all entries until you encounter an entry with d_tag == DT_NULL. That entry terminates the array. Reference.
