inlinevirtual |
file matching supporting * and ? - replacing regex which is not supported in all environments
virtual bool matches(const char* match){ int m_size = strlen(match); if (length() < m_size) return false; if (strncmp(this->chars,match,m_size-1)!=0) return false; if (match[m_size-1]=='*' || match[m_size-1]==this->chars[m_size-1] ){ return true; } return false; }
returns 1 (true) if there is a match returns 0 if the pattern is not whitin the line
the line is ended but char was expected
end of mask
if the line also ends here then the pattern match
try to restart the mask on the rest
