NAME¶

XSetState, XSetFunction, XSetPlaneMask, XSetForeground, XSetBackground - GC convenience routines

SYNTAX¶

int XSetState(Display *display, GC gc, unsigned long foreground, unsigned long background, int function, unsigned long plane_mask);

int XSetFunction(Display *display, GC gc, int function);

int XSetPlaneMask(Display *display, GC gc, unsigned long plane_mask);

int XSetForeground(Display *display, GC gc, unsigned long foreground);

int XSetBackground(Display *display, GC gc, unsigned long background);

ARGUMENTS¶

background

Specifies the background you want to set for the specified GC.

display

Specifies the connection to the X server.

foreground

Specifies the foreground you want to set for the specified GC.

function

Specifies the function you want to set for the specified GC.

gc

Specifies the GC.

plane_mask

Specifies the plane mask.

DESCRIPTION¶

TheXSetStatefunction sets the foreground, background, plane mask, and function componentsfor the specified GC.

XSetStatecan generateBadAlloc,BadGC,andBadValueerrors.

XSetFunctionsets a specified value in the specified GC.

XSetFunctioncan generateBadAlloc,BadGC,andBadValueerrors.

TheXSetPlaneMaskfunction sets the plane mask in the specified GC.

XSetPlaneMaskcan generateBadAllocandBadGCerrors.

TheXSetForegroundfunction sets the foreground in the specified GC.

XSetForegroundcan generateBadAllocandBadGCerrors.

TheXSetBackgroundfunction sets the background in the specified GC.

XSetBackgroundcan generateBadAllocandBadGCerrors.

DIAGNOSTICS¶

BadAlloc

The server failed to allocate the requested resource or server memory.

BadGC

A value for a GContext argument does not name a defined GContext.

BadValue

Some numeric value falls outside the range of values accepted by the request.Unless a specific range is specified for an argument, the full range definedby the argument's type is accepted.Any argument defined as a set ofalternatives can generate this error.
