XFreeColors(display, colormap, pixels, npixels, planes)
Display *display;
Colormap colormap;
unsigned long pixels[];
int npixels;
unsigned long planes;
display | Specifies the connection to the X server. |
colormap | Specifies the colormap. |
pixels | Specifies an array of pixel values that map to the cells in the specified colormap. |
npixels | Specifies the number of pixels. |
planes | Specifies the planes you want to free. |
All specified pixels that are allocated by the client in the colormap are freed, even if one or more pixels produce an error. If a specified pixel is not a valid index into the colormap, a BadValue error results. If a specified pixel is not allocated by the client (that is, is unallocated or is only allocated by another client) or if the colormap was created with all entries writable (by passing AllocAll to XCreateColormap()), a BadAccess error results. If more than one pixel is in error, the one that gets reported is arbitrary.
XFreeColors() can generate BadAccess , BadColor , and BadValue errors.
BadAccess | A client attempted to free a color map entry that it did not already allocate. |
BadAccess | A client attempted to store into a read-only color map entry. |
BadColor | A value for a Colormap argument does not name a defined Colormap. |
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 defined by the argument's type is accepted. Any argument defined as a set of alternatives can generate this error. |
