It appears to be the manual page for a GNU Awk (gawk) extension module. The complete list is:
$ find /usr/share/man/man3 -name '*3am*' | xargs dpkg -S
gawk: /usr/share/man/man3/readfile.3am.gz
gawk: /usr/share/man/man3/inplace.3am.gz
gawk: /usr/share/man/man3/ordchr.3am.gz
gawk: /usr/share/man/man3/revoutput.3am.gz
gawk: /usr/share/man/man3/readdir.3am.gz
gawk: /usr/share/man/man3/filefuncs.3am.gz
gawk: /usr/share/man/man3/revtwoway.3am.gz
gawk: /usr/share/man/man3/time.3am.gz
gawk: /usr/share/man/man3/rwarray.3am.gz
gawk: /usr/share/man/man3/fork.3am.gz
gawk: /usr/share/man/man3/fnmatch.3am.gz
I would guess the am stands for awk module.

In general, section 3 of the manual contains entries for library calls, which seems appropriate forgawklibraries, whereasfork()is carried out by the kernel and is therefore documented in section 2.

Yeah it seems that some libraries or "man page extensions" adds a postfix to the man page section number. In my system I've some prefixes likecpp,sslorperl.
