Function Documentation

char* getLine (  FILE *    file )

Returns a single line from FILE* file. Parameters: file  the file stream, from which the line is extracted this is a trivial function, which extracts a line (finished by ' ') and returns it (a char* to it). Returns: the line extracted, if none could be read, a zero length line is returned Referenced by mimeInit(), and readConfigFile().

int getNextValue (  int *    beg, int *    end, unsigned int    from, const char *    str )

Returns the next key seperatet by space chars of the passed str beginning at "from". Parameters: beg  returns the first valid char end  returns the last! valid char (not the one after it) from  pos in str, from where to check str  the string to check beg and *end and from are relative to str!! Returns: 0 on success, -1 otherwise Referenced by htMthdParse(), and mimeInit().
