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:

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).
