The values, -between 0.0 and 1.0, for the "red", green, and blue channels -are stored in -.IR *r , -.IR *g , -and -.IR *b , -respectively. -.PP -At least one of the values will be 1.0, none will be greater than -1.0, and none will be less than 0.0. It is guaranteed (unless the -resources file has been modified) that -.IR *r , -.IR *g , -and -.I *b -all will be 1.0 if -.I temp -is 6500. -.PP -You must call -.BR libred_init_colour (3) -before the first use of this function, -and you should call -.BR libred_term_colour (3) -after the last use of this function. -.SH "RETURN VALUE" -Upon successful completion, the function returns 0. On failure, -the function returns -1 and sets -.B errno -appropriately. -.SH ERRORS -The function may fail if: -.TP -.B EOVERFLOW -The colour temperature lookup table is smaller than it should be. -.TP -.B EDOM -If -.I temp -is less than -.B LIBRED_LOWEST_TEMPERATURE -(which is 1000.) -.PP -The function may also fail for any reason specified for -.BR pread (3), -and set the value of -.B errno -to the same values. -.SH "FUTURE DIRECTIONS" -It is possible that the behaviour is changed to loading the -colour temperature lookup table rather than just open a -file descriptor to it. -.SH "SEE ALSO" -.BR libred.h (0), -.BR libred (7), -.BR libred_init_colour (3), -.BR libred_term_colour (3) -- cgit v1.2.3-70-g09d2
