Give it a sniff!
Seriously, tho, you will be much happier with life if you write 'lil fgetc() or read() functions like me
C programming resources:
GNU C Function and Macro Index -- glibc reference manual
The C Book -- nice online learner guide
Current ISO draft standard
CCAN -- new CPAN like open source library repository
3 (different) GNU debugger tutorials: #1 -- #2 -- #3
cpwiki -- our wiki on sourceforge
are you scanning the input into the buffer? not sure what you mean exactly by "after i do scanf i want to check if the buffer is clean..."Originally Posted by transgalactic2
dosent scanf by definition take all chars from input buffer and transfer to the buffer inside your program?
hangon which buffer??? the terminal or your C buffer???
No. It doesn't transfer anything, it converts the input characters according to the conversion specifiers. Characters which are converted are removed from the buffer. If a conversion fails, the characters which did not convert REMAIN in the buffer.
And we are talking about the stdio buffer, not the terminal buffer.
Code://try //{ if (a) do { f( b); } while(1); else do { f(!b); } while(1); //}
use fgets/sscanf pair
All problems in computer science can be solved by another level of indirection,
except for the problem of too many layers of indirection.
