c - Comparing defined raw data using preprocessor -


i have defined raw data in header file (which generated automatically), this:

#defined raw_data 0x11, 0x20, 0x55, 0x00, x044

the aim check specific parameter of raw_data in compilation time , if wrong throw #error.

for instance, during compilation, preprocessor should check if 2nd parameter of raw_data (in case 0x20) 0x20, if not throw #error.

the main problem, how access specific parameter in defined raw_data, somehow possible?

p.s. using keil compiler in c.

#define raw_data 0x11, 0x20, 0x55, 0x00, x044 #define x_get_second_par(par) get_second_par(par) #define get_second_par(p1,p2,p3,p4,p5) p2  #if x_get_second_par(raw_data) != 0x20 #error "2nd parameter shall 0x20" #endif

for specific parameter checking. it's not elegant.

i have read ( how make choices in radiobuttons reactive in shiny? ) shows me how update radiobutton s in reactive way. however, when try , update 2 sets of buttons same data, 1 set renders. example: server: # create example data wafer <- rep(c(1:3), each=3) length <- c(1,1,2,1,1,1,3,5,1) width <- c(3,1,6,1,1,1,1,1,6) dd <- data.frame(wafer, length, width) shinyserver(function(input, output, session){ # create reactive dataframe store data values <- reactivevalues() values$df <- data.frame() # lengths , widths of wafer user input <- eventreactive(input$do, { subset(dd, wafer %in% input$wafer, select = length:width) }) # update reactive data frame lengths , widths have been selected user input observe({ if(!is.null(a())) { values$df <- rbind(isolate(values$df), a()) } }) output$wl <- renderdatatable({ a() }) # update radio buttons unique length , widths stored in values$df # ever "observe" put first in co...

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
