Passing pathname argument in glob() function

[Sn0wcra5h]

Is it possible to pass a pathname to glob()?

I have sample code that I've tried to modify to accept a pathname and use this to search the path given. The code below only searches the present working directory.

Can anyone suggest a good glob() tutorial or article to reference?

int	main(int argc, char *argv[])
{
	glob_t	paths;
	int		csource;
	char	**p;
	
	printf("argv[0] = %s\n", argv[0]);
	printf("argv[1] = %s\n", argv[1]);  /* Argument I want to use as pathname */
	
	/* Find all ".c" files in given directory*/
	csource = glob("*.c", 0, NULL, &paths);
	
	if (csource == 0)
	{
		for (p=paths.gl_pathv; *p != NULL; ++p)
			puts(*p);
		globfree(&paths);
	}

What you'd want to do is glue the pathname together with the pattern using something like snprintf(). glob("/some/path/*.c", ..) would be how the actual call would look.

As for tutorials, sorry, I don't know of any, apart from whatever examples your man pages might contain.

Thanks cas.

I did try using snprintf, but I'm not able to get the glob command to work with my string created with snprintf. My output is:

# ./globprog /home/myuser
1: This is argv[0] = ./globprog
2: This is argv[1] = /home/myuser
3: PATH = /home/myuser
This is the fullpath: "/home/myuser*.c"
Glob error. globresult = 16384

My code is below:

int	main(int argc, char *argv[])
{
	glob_t	paths;
	int	globresult;
	char	fullpath[MAX_LEN+1],
		**p;
			
	printf("1: This is argv[0] = %s\n", argv[0]);
	printf("2: This is argv[1] = %s\n", argv[1]);
	printf("3: PATH = %s\n", argv[1]);
	
	snprintf(fullpath, MAX_LEN, "\"%s/*.c\"", argv[1]);
	printf("This is the fullpath: %s\n", fullpath); 
	
	/* Find all ".c" files in specified directory and store in paths structure*/
	globresult = glob(fullpath, 0, NULL, &paths);

Don't put quotes around the path. glob() will look for a path that starts with a quote if you do that, and of course no such path will exist.
