i = Ignore case
m = Multilines (affects ^ and $ so that they match
    the start/end of a line rather than matching the
    start/end of the string).

    even new line characters).
x = Pattern extension (ignore whitespace and # comments).

Описание

Precompile a regular expression.

Пометка

Use this if you intend on using the same expression multiple times.
Pass the regex handle returned here to regex_match_c to check for matches.

Пометка

This handle is automatically freed on map change.  However,
if you are completely done with it before then, you should
call regex_free on this handle.

Пометка

Consider using regex_compile_ex instead if you want to use PCRE_* flags.
