## 116. SLang_input_pending

Synopsis

  Check to see if input is pending

Usage

  `int SLang_input_pending (int tsecs)`

Description

  `SLang_input_pending` may be used to see if an input character is available to be read without causing `SLang_getkey` to block. It will wait up to `tsecs` tenths of a second if no characters are immediately available for reading. If `tsecs` is less than zero, then `SLang_input_pending` will wait `-tsecs` milliseconds for input, otherwise `tsecs` represents `1/10` of a second intervals.

Notes

  Not all systems support millisecond resolution.
