re_comp() is used to compile
the null-terminated regular expression pointed to by
regex. The compiled
pattern occupies a static area, the pattern buffer, which is
overwritten by subsequent use of
regex is NULL, no operation is
performed and the pattern buffer_zsingle_quotesz_s contents are not
re_exec() is used to assess
whether the null-terminated string pointed to by
string matches the previously
re_comp() returns NULL on
successful compilation of
regex otherwise it returns a
pointer to an appropriate error message.
re_exec() returns 1 for a
successful match, zero for failure.
For an explanation of the terms used in this section, see attributes(7).
These functions are obsolete; the functions documented in regcomp(3) should be used instead.
