Symbol

Meaning

__STDC__

Defined to 1. This identifies lcc-win32 as an ANSI C compiler.

__DATE__

Contains the current compilation date in the format: MMM DD YYY as a character string.

__TIME__

Contains the current time as a character string in the format: HH:MM:SS Note that this “timer” does not change, even if the compilation takes a long time.

__FILE__

Contains the name of the current file without any path component as a character string.

__func__

This symbol will be expanded by the compiler to a character string containing the name of the current function being compiled, or the character string “<none>”if no function is currently being defined.[2]

__LINE__

This symbol will be expanded to an integer containing the current line number in the source file. Note that this line number can be changed to an arbitrary value with the # line directive.

__LCC__

Allows you to conditionally compile source for the lcc compiler.

__LCCOPTIMLEVEL

If optimization is on, i.e., the –O option was given in the command line or if the #pragma optimize was parsed, this preprocessor variable will have the value one. If no optimizations are active, its value is zero.

__LCCDEBUGLEVEL

If the compiler is called with the –g<n> option (debug level n) the value of LCCDEBUGLEVEL is n. If there is no –g in the compiler’s command line, then its value is zero.

RC_INVOKED

Defined by the resource compiler when active.

WINVER

Contains a two-byte number with the major version number of windows in the high byte, and the minor version number in the low byte. This value is determined at compile time. Note that this predefined symbol CAN be changed with the #undef directive.

WIN32

_WIN32

Defined to 1. Note that contrary to other predefined symbols, this symbol can be undefined with the #undef directive.

__int64

Defined as the long long integer type for compatibility with the Microsoft compiler.

__cdecl

__inline

_cdecl

_huge

Defined to the empty string for compatibility reasons.
