bool Regex::extract_prefix ( const char *  regex, size_t  regex_len, const char **  output, size_t *  output_len, DynamicBuffer &  buf  )

static

Extracts a fixed prefix from regular expression.

This function extracts a fixed prefix from the regular expression defined by regex and regex_len. A candidate string which maches the regex implies that the string begins with the fixed prefix. A fixed prefix can only be extacted from a regular expression that begins with the '^' character and is followed by some number of non-qualified, non-meta characters.

Parameters

regex	Pointer to regular expression
regex_len	Length of regular expression
output	Address of output pointer to beginning of prefix
output_len	Address of output length to hold length of prefix
buf	Buffer to hold prefix if expansion was required

Returns

true if a valid prefix was extracted, false otherwise.
