how to add this function to the aclole.m4

[Ralph Blach]

I want to add this function to the aclocal.m4

How do I do it.

This should check for function prototypes.

Thanks

the configure.ac has

> AC_CHECK_FUNC_PROTO(gethostname, unistd.h)
> AC_CHECK_FUNC_PROTO(getrusage, sys/resource.h)
> AC_CHECK_FUNC_PROTO(isfdtype, sys/stat.h)
> AC_CHECK_FUNC_PROTO(pselect, sys/select.h)
> AC_CHECK_FUNC_PROTO(shm_open, sys/mman.h)
