GETCMAP(9.2) GETCMAP(9.2) NAME getcmap - read a color map from a file SYNOPSIS #include <libg.h> #include <fb.h> int getcmap(char *name, uchar *map) DESCRIPTION Getcmap retrieves the named colormap and stores it in map. Usually name is the name of a colormap file (see cmap(9.6)) or a picfile with a CMAP= attribute. If the file is not found, it is sought in /lib/fb/cmap. If the file cannot be found, and its name has the form gammanumber, a colormap is fabricated with all three chan- nels of its nth entry set to 255×(n/255)1/number. If the name is just gamma, number=2.3 is assumed. There is no putcmap, because write (in read(2)) can do the job.
