but i didn't understand this line mkdir("/dev/properties", S_IRWXU | S_IXGRP | S_IXOTH);

please help me to understand this line

but i didn't understand this line mkdir("/dev/properties", S_IRWXU | S_IXGRP | S_IXOTH);

you're making a new directory

that i known , but what's the mean of this S_IRWXU | S_IXGRP | S_IXOTH

Have you tried using the almighty google?

yes but no luck

Google S_IRWXU

yeah i google it and i thing this is the read and write permission which need to set on that folder which is created by the mkdir am i right??

linux

thanks for your help😄

Something like that. I don't really know all of the details.

void property_init() { mkdir("/dev/properties", S_IRWXU | S_IXGRP | S_IXOTH); CreateSerializedPropertyInfo(); if (__system_property_area_init()) { LOG(FATAL) << "Failed to initialize property area"; } if (!property_info_area.LoadDefaultPath()) { LOG(FATAL) << "Failed to load serialized property info file"; }

need one more help guys in this funtion , in this statement if (__system_property_area_init()), here __system_property_area_init() what's this?

Hi, would you please explain me the highlighted section?

read it and ask specific questions, please

I don't understand the highlighted part, all of it. Just need a better and broader explanation.

Ask specific questions, please

If you say 'all of it' that implies that you dont understand ANY word in that sentence

Any group for CSharp??

If we undef getchar and putchar, and then use them in the program, what happens to their functionality compared to when we don't undef them.

@linuxer4fun The last sentence, to avoid the runtime overhead of a function all call per character processed. What it implies?

Preprocessor is simple text replacement #define one 1 ... ... int i = one; Before building int i = 1; Now build. On gcc you can view preprocessor output with $ gcc -E file.c -o output.c

Enable -Wall and -Wextra in your compiler options.

change %i with %d and scanf("%d",&a);

Why did you use %i? Use %d as said above
