NAME
fiu-ctrl - a script to remote control programs using libfiu SYNOPSIS
fiu-ctrl [options] PID [PID ...] DESCRIPTION
fiu-ctrl is a script to enable/disable failure points in running programs that are using libfiu(3). Programs are usually launched using fiu-run(1), which enables libfiu's remote control capabilities without the need to modify the program's code. For additional documentation, go to the project's website at http://blitiri.com.ar/p/libfiu. OPTIONS
-c command Run the given libfiu remote control command before executing the program (see below for reference). -f ctrlpath Set the default prefix for remote control over named pipes. Defaults to "$TMPDIR/fiu-ctrl", or "/tmp/fiu-ctrl" if "$TMPDIR" is not set, which is the usually correct for programs launched using fiu-run(1). Remote control commands are of the form "command param1=value1,param2=value2". Valid commands are: 'enable name=NAME' Enables the NAME failure point unconditionally. 'enable_random name=NAME,probability=P' Enables the NAME failure point with a probability of P. 'disable name=NAME' Disables the NAME failure point. All of the enable* commands can also optionally take failnum and failinfo parameters, analogous to the ones taken by the C functions. EXAMPLES
The following command will tell the process running with PID 12345 to enable the failure point posix/io/read with a 25% of probability to fail, and the failure point libc/mm/malloc with a 5% of probability to fail: fiu-ctrl -c 'enable_random name=posix/io/*,probability=0.25' -c 'enable_random name=libc/mm/*,probability=0.05' 12345 And the following will tell the same process to disable the previously enabled failure point posix/io/read: fiu-ctrl -c 'disable name=posix/io/read' 12345 SEE ALSO

NAME
readkey - Returns the next character from the keyboard buffer. Allegro game programming library. SYNOPSIS
#include <allegro.h> int readkey(); DESCRIPTION
Returns the next character from the keyboard buffer, in ASCII format. If the buffer is empty, it waits until a key is pressed. You can see if there are queued keypresses with keypressed(). The low byte of the return value contains the ASCII code of the key, and the high byte the scancode. The scancode remains the same whatever the state of the shift, ctrl and alt keys, while the ASCII code is affected by shift and ctrl in the normal way (shift changes case, ctrl+letter gives the position of that letter in the alphabet, eg. ctrl+A = 1, ctrl+B = 2, etc). Pressing alt+key returns only the scan- code, with a zero ASCII code in the low byte. For example: int val; ... val = readkey(); if ((val & 0xff) == 'd') /* by ASCII code */ allegro_message("You pressed 'd' "); if ((val >> 8) == KEY_SPACE) /* by scancode */ allegro_message("You pressed Space "); if ((val & 0xff) == 3) /* ctrl+letter */ allegro_message("You pressed Control+C "); if (val == (KEY_X << 8)) /* alt+letter */ allegro_message("You pressed Alt+X "); This function cannot return character values greater than 255. If you need to read Unicode input, use ureadkey() instead. SEE ALSO
