A regexp that is qualified by a state will only be 417c478bd9Sstevel@tonic-gate * used when the state is entered (using the BEGIN <state> command). (The 427c478bd9Sstevel@tonic-gate * exception to this rule, is that rules defined in the default state are 437c478bd9Sstevel@tonic-gate * available in all states.) 447c478bd9Sstevel@tonic-gate * 457c478bd9Sstevel@tonic-gate * poolcfg.l makes use of type states, one for each of the poolcfg(1) 467c478bd9Sstevel@tonic-gate * supported data types: 477c478bd9Sstevel@tonic-gate * 487c478bd9Sstevel@tonic-gate * ISTATE => int64_t 497c478bd9Sstevel@tonic-gate * USTATE => uint64_t 507c478bd9Sstevel@tonic-gate * BSTATE => uchar_t 517c478bd9Sstevel@tonic-gate * SSTATE => const char * 527c478bd9Sstevel@tonic-gate * DSTATE => double 537c478bd9Sstevel@tonic-gate * 547c478bd9Sstevel@tonic-gate * and a further state, CPUSTATE, to indicate the difference between matching 557c478bd9Sstevel@tonic-gate * a valid "name" (i.e. id) for a cpu and a valid name for other components of 567c478bd9Sstevel@tonic-gate * libpool. 577c478bd9Sstevel@tonic-gate * 587c478bd9Sstevel@tonic-gate * When a token indicating a variable declaration is matched, the corresponding 597c478bd9Sstevel@tonic-gate * state is saved in the state variable. Once the assignment ('=') token is 607c478bd9Sstevel@tonic-gate * matched, the stored state is entered and the additional state specific 617c478bd9Sstevel@tonic-gate * matching regular expressions become available. Once a state specific 627c478bd9Sstevel@tonic-gate * token is matched, the default state is restored. 63*2a8bcb4eSToomas Soome * 647c478bd9Sstevel@tonic-gate */ 657c478bd9Sstevel@tonic-gate #include <stdlib.h> 667c478bd9Sstevel@tonic-gate #include <sys/types.h> 677c478bd9Sstevel@tonic-gate #include <assert.h> 687c478bd9Sstevel@tonic-gate #include <string.h> 697c478bd9Sstevel@tonic-gate #include <errno.h> 707c478bd9Sstevel@tonic-gate #include <libintl.h> 717c478bd9Sstevel@tonic-gate 727c478bd9Sstevel@tonic-gate #include <pool.h> 737c478bd9Sstevel@tonic-gate #include "utils.h" 747c478bd9Sstevel@tonic-gate #include "poolcfg.h" 757c478bd9Sstevel@tonic-gate #include "poolcfg_grammar.h" 767c478bd9Sstevel@tonic-gate 777c478bd9Sstevel@tonic-gate static int lex_lineno = 1;
