IDC compatibility module
This file contains IDA built-in function declarations and internal bit
definitions. Each byte of the program has 32-bit flags (low 8 bits keep
the byte value). These 32 bits are used in GetFlags/SetFlags functions.
You may freely examine these bits using GetFlags() but the use of the
SetFlags() function is strongly discouraged.
This file is subject to change without any notice.
Future versions of IDA may use other definitions.
