Spacing

• indentation: one tab stop
  
• one space before opening parenthesis
  
• no space after opening parenthesis
  
• one space after a comma: foo (x, y) not foo (x,y)
  
• one space around operators (x == y, x && y, x != y, x = y, ...)
  
• no space around . and ->
  

Bracing

• opening brace on the same line as if, else, for, switch, case & while
  
• else on the same line as if closing brace
  
• braces in case statements allowed (if new scope needed) but not required
  
• open and close braces for functions on own separate lines.
  
• opening and closing braces required even for single line if, for, while statements
  

Naming

• use low case except in SAF libraries which should follow the SAF coding style guidelines.
  
• use descriptive names
  
• words separated with underscore
  
• functions preferably named object_verb
  

Misc

• Max 3 levels of indentation recommended
  
• Max line length 80 chars or less
  
• Functions should be short and do one thing
  
• Pointer comparisons with NULL not 0
  
• Comments, see example
  
• C++ comments not allowed
  
• No multiple statements on a single line
  
• gotos OK for centralized exit of functions
  
• When in doubt, check Steven's code and K&R C book
