Function Documentation

int check_byte ( const char *  val  ) 

Check to see if val is a valid byte value. If not, generate an error message using parser_error(). There are two versions of check_byte(), one which calls parser_error() and prints an error message to stderr an one which calls parser_error() and generates and Error object.

Returns:
Returns: True if val is a byte value, False otherwise.

Definition at line 144 of file parser-util.cc.

void save_str ( char *  dst,
const char *  src,
const int  line_num 
)

Given a string (const char *src), save it to the temporary variable pointed to by dst. If the string is longer than ID_MAX, generate and error indicating that src was truncated to ID_MAX characters during the copy operation. There are two versions of this function; one calls the version of parser_error() which writes to stderr. The version which accepts the parser_arg *arg argument calls the version of parser_error() which generates and Error object.

Returns:
void
