Dear Sirs,
I'm currently implementing a program which will run thousands and
thousands times. It uses regular expressions.
something really simple, like
regex_t re;
regcomp(&re,"^[0123456789abcdefghijklmnopqrstuvwxyz]{1,8}$",
REG_EXTENDED+REG_ICASE);
return(!regexec(&re,name,0,0,0));
so, questions are:
1) is it faster to "compile" regex once and load it from file every time
program starts ?
2) how to store in a file data of type "regex_t" ??
Regards, (Наилучшие пожелания)
