XkbSetDebuggingFlags(3) XKB FUNCTIONS XkbSetDebuggingFlags(3)
NAME
XkbSetDebuggingFlags - Change the values of any of the debug controls
SYNOPSIS
Bool XkbSetDebuggingFlags (Display *display, unsigned int mask, unsigned int flags, char
*msg, unsigned int ctrls_mask, unsigned int ctrls, unsigned int *ret_flags,
unsigned int *ret_ctrls);
ARGUMENTS
- display
connection to X server
- mask mask selecting debug output flags to change
- flags
values for debug output flags selected by mask
- msg message to print right now
- ctrls_mask
mask selecting debug controls to change
- ctrls
values for debug controls selected by ctrls_mask
- ret_flags
resulting state of all debug output flags
- ret_ctrls
resulting state of all debug controls
DESCRIPTION
The debugging aids are intended for use primarily by Xkb implementors and are optional in
any implementation.
There are two bitmasks that may be used to control debugging. One bitmask controls the
output of debugging information, and the other controls behavior. Both bitmasks are ini-
tially all zeros.
To change the values of any of the debug controls, use XkbSetDebuggingFlags.
XkbSetDebuggingFlags modifies the debug output flags as specified by mask and flags, modi-
fies the debug controls flags as specified by ctrls_mask and ctrls, prints the message
msg, and backfills ret_flags and ret_ctrls with the resulting debug output and debug con-
trols flags.
When bits are set in the debug output masks, mask and flags, Xkb prints debug information
corresponding to each bit at appropriate points during its processing. The device to which
the output is written is implementation-dependent, but is normally the same device to
which X server error messages are directed; thus the bits that can be set in mask and
flags is implementation-specific. To turn on a debug output selection, set the bit for the
output in the mask parameter and set the corresponding bit in the flags parameter. To turn
off event selection for an event, set the bit for the output in the mask parameter and do
not set the corresponding bit in the flags parameter.
When bits are set in the debug controls masks, ctrls_mask and ctrls, Xkb modifies its
behavior according to each controls bit. ctrls_mask and ctrls are related in the same way
that mask and flags are. The valid controls bits are defined in Table 1.

XkbSetDebuggingFlags returns True if successful and False otherwise. The only protocol
error it may generate is BadAlloc, if for some reason it is unable to allocate storage.
XkbSetDebuggingFlags is intended for developer use and may be disabled in production X
servers. If it is disabled, XkbSetDebuggingFlags has no effect and does not generate any
protocol errors.
The message in msg is written immediately. The device to which it is written is implemen-
tation dependent but is normally the same device where X server error messages are
directed.
RETURN VALUES
True The XkbSetDebuggingFlags function returns True when successful.
False The XkbSetDebuggingFlags function returns False when not successful.
DIAGNOSTICS
BadAlloc Unable to allocate storage
