Allocating string space

I have many routines in GraphApp.e which use allocate_string(), for example:

global function execapp(sequence cmd)
 return c_func(execapp_,{allocate_string(cmd)})
end function --( in c:  int    execapp(char *cmd) )

Question:
Am I causing major memory leaks?
Does allocate_string allocate a whole new string with a c-style pointer, and if
so, does it free this string once the function is exited?

Would it be better to write this as:
global function execapp(sequence cmd)
atom s
 s = allocate_string(cmd)
 return c_func(execapp_,{s})
end function

Or like this:
global function execapp(sequence cmd)
atom s
object result
 s = allocate_string(cmd)
 result = c_func(execapp_,{s})
 free(s)
 return result
end function

Thanks,
