* "gets" reads a string from the standard input, and returns
|
|
* its argument (NULL on end of file). The newline at the
|
|
* end of the string is replaced by a NULL.
|
|
*
|
|
* Calling sequence:
|
|
* addr = gets(saddr)
|
|
* Where:
|
|
* saddr -> where the string is to go (no bounds check)
|
|
* addr = saddr if all ok, NULL o.w.
