flex lexer - lex : How to override YY_BUF_SIZE -
according manual yy_buf_size
16k
, need override it. however, manual not specify how override it, nor find command line option this. can please indicate how change this. in generated source yy_buf_size
defined follows:
#ifndef yy_buf_size #define yy_buf_size 16384 #endif
so there may way override before this.
in own code, #define yy_buf_size whatever value want. long compile code compiler sees definition first, #ifndef guard prevent default value being set.
