* Name: gets
|
|
*
|
|
* Description:
|
|
* gets() reads a line from stdin into the buffer pointed to by s until
|
|
* either a terminating newline or EOF, which it replaces with '\0'. No
|
|
* check for buffer overrun is performed
|
|
*
|
|
* This API should not be used because it is inherently unsafe. Consider
|
|
* using fgets which is safer and slightly more efficient.
