[c] recursive function for finding matched String with wildcard *

wildcard * is used to search for a particular character(s) for zero or more times.

static int	word_compare(char **filename, char *wild, int *idx)
{
	while (**filename && wild[*idx] && wild[*idx] != '*')

		}
		else
			return (0);
	}
	if (wild[*idx] != '*' && **filename != wild[*idx])
		return (0);
	if (!wild[*idx] && **filename)
		return (0);
	return (1);
}

{

	int	i;

	idx = 0;
	while (wild[idx])
	{
		if (wild[idx] == '*')
		{
			i = ft_strichr(filename, wild[idx + 1]);  // find the character right after *
			while (i >= 0)
			{

					return (1);
