That is just like writing a script, not calling system calls
find is based on the nftw() call and uses stat semantics - it returns among other things a struct stat.
To answer your question--
You should consider system(). It calls execl for you and then calls waitpid.
The reason to call syscalls directly in C instead of using execl() is to eliminate process creation which has a lot of overhead that you have in a shell script. system() and execl() are doing nothing you cannot do in a shell script in this case.
open, creat, read, write, lseek and close
Are they all primitive?
:confused:
*Another Question: is there a different between a system call, and an i/o system call? (2 Replies)
Hi,
I'm new to UNIX system calls. Can someone share your knowledge as to how exactly system calls should be executed?

ODOT(1) User Contributed Perl Documentation ODOT(1)NAME
Odot - A task list manager
SYNOPSIS
odot [FILE]
DESCRIPTION
Odot is a task list manager that organizes tasks hierarchically and emphasizes ones which are due.
You can add tasks by either using the "Add" button at the bottom or the right click context menu. A new row will be appended and you can
immediately start editing it.
Tasks can be modified by highlighting the row and activating the cell that should be edited. Cells are activated by either clicking on
them or by pressing [Enter] when they are focused. Existing tasks can be deleted with the "Delete" button, the equivalent menu entry or by
hitting the [Del] key.
When editing a node, you can press [Up] or [Down] to commit changes to the current node and move to and edit the previous or next node.
You can reorder tasks by dragging and dropping them wherever you like or by using [Alt] plus the arrow key that denotes the direction you
want. Indenting and unindenting can also be achieved via [Tab] and [Backspace] respectively. You can sort the children of a task alpha-
betically by using the "Sort" or the "Sort Recursively" menu item.
You can cut / copy and paste nodes including all their children with [Ctrl]+[x] / [Ctrl]+[C] and [Ctrl]+[v].
Every change is undoable by pressing [Ctrl]+[z] and every undone change is redoable by pressing [Ctrl]+[Shift]+[z].
If its due date is only two days ahead of the current date, the task will be printed bold. If a task is due today, it's printed bold and
italic. If a task is overdue, it's printed italic.
If a due task is hidden because one of its ancestors is collapsed, these ancestors are printed underlined.
OPTIONS
You can specify where Odot should store the tasks by passing a filename as a commandline argument. The default is ~/.odot.
