| 39 | The <tt>socket</tt> namespace contains the namespace tables for all | ||
| 40 | LuaSocket modules as well as function that didn't belong in any specific | ||
| 41 | module, functions that are so commonly used that deserve a shortcut and a | ||
| 42 | few constants. | ||

| 67 | <p class=parameters> | ||
| 68 | <tt>Function</tt> is a function that calls | ||

| 71 | |||

| 91 | </p> | ||
| 92 | |||
| 93 | <p class=return> | ||
| 94 | The function returns ret<sub>1</sub>, ret<sub>2</sub> ... ret<sub>N</sub> if | ||
