Function Documentation

void hash_include_tally	(	char const *	arg,
		size_t	arglen,
		canonical_string_const_h	sym_val
	)

Tally an occurrence of an hash-include argument.

Parameters:

arg	The start of the hash-include argument.
arglen	The length of the hash-include argumentument.
sym_val	Where the hash-include argument is a defined symmbol, sym_def contains the canonicalised final value of that symbol, else NULL.

If no hash-include argument matching arg exists in in the includes table, then a new hash-include argument is added to the table. If a matching hash-include argument is already in the table then that hash-include argument is given the definition sym_val if sym_val is not NULL and if the existing hash-include argument does not already have that definition. If sym_val is NULL then the matching hash-include argument is made undefined if it currently has a definition.

The occurrence of the hash-include argument is reported on stdout if the same hash-include argument has not already been seen or if --once is not in effect. If the hash-include argument is reported and sym_val is not NULL then the hash-include argument will be reported as a symbol that resolves sym_val.
