Regex
7.3.2 BSD Searching
Searching the Berkeley UNIX way means searching in a string
starting at its first character and trying successive positions within
it to find a match. Once you've compiled a pattern using re_comp
(see section 7.3.1 BSD Regular Expression Compiling), you can ask Regex
to search for that pattern in a string using:
| | int
re_exec (char *string)
|
string is the address of the null-terminated string in which you
want to search.
re_exec returns either 1 for success or 0 for failure. It
automatically uses a GNU fastmap (see section 7.1.6 Searching with Fastmaps).
