abstract:
We are yet to call regfree in the startup process to free memory allocated by regcomp. I guess issues will be there also since it did not work in my test program. Good old segmentation fault.
Read somewhere on the net that we cant copy regex_t since its an opaque and cant just copy it.
Any suggestions friends?
Hi,
I am trying to create a map in C++ which will have the regular expression and the corresponding compiled regular form returned by regcomp. It will be something like this:
map <string, regex_t> my_var;
In the startup process we read the regular expressions and store corresponding regex_t variable value in the map. regex_t variable is something like this:
regex_t re;
reslt = regcomp(&re, regex_string, REG_EXTENDED|REG_NOSUB);
then we do:
my_var[regex_string]=re;
.
In other file we use this map to read the re and pass it on to regexec.
It compiles well. But on running we get coredump.
