Detailed Description

These macros allow the handling of small texts and tokens.

For the following tokens, the macro P99_TOK_EQ will work.

• decimal numbers: 0 ... 159
• keywords: _Bool _Complex _Imaginary auto break case char const continue default do double else enum extern float for goto if inline int long register restrict return short signed sizeof static struct switch typedef union unsigned void volatile while

Warning

Non-functional macros cannot be captured by this mechanism since they will be expanded before we may actually handle them. This concerns in particular the following tokens that are defined to be macros: NULL and and_eq bitand bitor bool compl false not not_eq offsetof or or_eq true xor xor_eq
