NAME
regex.h, regex - regular expression matching types SYNOPSIS
#include <regex.h> DESCRIPTION
The <regex.h> header defines the structures and symbolic constants used by the regcomp(), regexec(), regerror(), and regfree() functions. See regcomp(3C). The structure type regex_t contains the following member: size_t re_nsub number of parenthesized subexpressions The type size_t is defined as described in <sys/types.h>. See types.h(3HEAD). The type regoff_t is defined as a signed integer type that can hold the largest value that can be stored in either a type off_t or type ssize_t. The structure type regmatch_t contains the following members: regoff_t rm_so byte offset from start of string to start of substring regoff_t rm_eo byte offset from start of string of the first character after the end of substring Values for the cflags parameter to the regcomp function are as follows: REG_EXTENDED use extended regular expressions REG_ICASE ignore case in match REG_NOSUB report only success or fail in regexec() REG_NEWLINE change the handling of NEWLINE character Values for the eflags parameter to the regexec() function are as follows: REG_NOTBOL The circumflex character (^), when taken as a special character, does not match the beginning of string. REG_NOTEOL The dollar sign ($), when taken as a special character, does not match the end of string. The following constants are defined as error return values: REG_NOMATCH regexec() failed to match. REG_BADPAT Invalid regular expression. REG_ECOLLATE Invalid collating element referenced. REG_ECTYPE Invalid character class type referenced. REG_EESCAPE Trailing '' in pattern. REG_ESUBREG Number in fIdigit invalid or in error. REG_EBRACK "[]" imbalance. REG_EPAREN "()" or "()" imbalance. REG_EBRACE "" imbalance. REG_BADBR Content of "" invalid: not a number, number too large, more than two numbers, first larger than second. REG_ERANGE Invalid endpoint in range expression. REG_ESPACE Out of memory. REG_BADRPT '?', '*', or '+' not preceded by valid regular expression. REG_ENOSYS Reserved. ATTRIBUTES
