Function Documentation

static void CON_FlushIn ( void ) [static]

Flush stdin, I suspect some terminals are sending a LOT of shit.

Todo:: relevant?

Definition at line 61 of file unix_console.c.

Referenced by Sys_ConsoleInput().

void Sys_ConsoleInit ( void )

Initialize the console input (tty mode if possible).

Definition at line 225 of file unix_console.c.

References Com_Printf(), qfalse, qtrue, stdinActive, Sys_IsATTY(), Sys_TTYConsoleHistoryClear(), Sys_TTYConsoleSigCont(), TTY_eof, TTY_erase, TTY_tc, and ttyConsoleActivated.

const char* Sys_ConsoleInput ( void )

void Sys_ConsoleOutput ( const char * string )

Note:: if the user is editing a line when something gets printed to the early console then it won't look good so we provide CON_Hide and CON_Show to be called before and after a stdout or stderr output

Definition at line 399 of file unix_console.c.

References COLORED_GREEN, qfalse, qtrue, and Sys_ShowConsole().

void Sys_ConsoleShutdown ( void )

Shutdown the console.

Note:: Never exit without calling this, or your terminal will be left in a pretty bad state
