It's not homework. I'm looking to know mostly out of curiosity, but you could argue that using wildcards is bad anyway. If there's a million files in the directory, that's a million rm processes (obviously not all simultaneous, but still). It's not bullet-proof:
/*skipped the code*./
On top of that, it's not easy to use from, say, an exec() call. You need the infrastructure of a shell.
So my question stands.
I dont think you have that right.. a million processes is not a million rm processes. Its all those million files as arguments to one rm process. Now that might fail due to too many arguments (any command can handle only a finite number).
I will give you your second argument about not being easy to use from an exec() call.
Why don't you use a slightly modified form of the find command that ppierald gave:
That, by the way, would be a million rm processes (one for each file/directory that the find command would output).

getexecname
getexecname(3C) Standard C Library Functions getexecname(3C)NAME
getexecname - return pathname of executable
SYNOPSIS
#include <stdlib.h>
const char *getexecname(void);
DESCRIPTION
The getexecname() function returns the pathname (the first argument of one of the exec family of functions; see exec(2)) of the executable
that started the process.
Normally this is an absolute pathname, as the majority of commands are executed by the shells that append the command name to the user's
PATH components. If this is not an absolute path, the output of getcwd(3C) can be prepended to it to create an absolute path, unless the
process or one of its ancestors has changed its root directory or current working directory since the last successful call to one of the
exec family of functions.
RETURN VALUES
If successful, getexecname() returns a pointer to the executables pathname; otherwise, it returns 0.
USAGE
The getexecname() function obtains the executable pathname from the AT_SUN_EXECNAME aux vector. These vectors are made available to dynam-
ically linked processes only.
A successful call to one of the exec family of functions will always have AT_SUN_EXECNAME in the aux vector. The associated pathname is
guaranteed to be less than or equal to PATH_MAX, not counting the trailing null byte that is always present.
