I'm trying to debug a gtk+ app so I'm trying to learn some basic gtk+
and failing :(
Can anyone splain to me what these lines mean:
typedef enum
{
G_CONNECT_AFTER = 1 << 0,
G_CONNECT_SWAPPED = 1 << 1
} GConnectFlags;
In particular I don't understand what the << operator is doing.
When I was young << meant bitwise shift to the left. When I got old
and tried to learn c++ it was a way to print a string to the terminal.
Any clues would be welcome. <type slowly and use small words, please>
Bit shift. gtk+ is written in C, so '<<' is always bit shifting. Enums
are basically constants, and they're hardcoding the values so they can
be OR'd together.
