LIBRARY

Standard C library (libc)

SYNOPSIS

#include <regex.h>

typedef struct { size_t re_nsub; /* Number of parenthesized subexpressions */ } regex_t;

typedef struct { regoff_t rm_so; /* Byte offset from start of string
                           to start of substring */ regoff_t rm_eo; /* Byte offset from start of string to
                           the first character after the end of
                           substring */ } regmatch_t;

typedef /* ... */ regoff_t;

DESCRIPTION

regex_t: This is a structure type used in regular expression matching. It holds a compiled regular expression, compiled with regcomp(3).
regmatch_t: This is a structure type used in regular expression matching.
regoff_t: It is a signed integer type capable of storing the largest value that can be stored in either an ptrdiff_t type or a ssize_t type.
