Method

GLibScannerunexp_token

Declaration [src] 

void
g_scanner_unexp_token (
  GScanner* scanner,
  GTokenType expected_token,
  const gchar* identifier_spec,
  const gchar* symbol_spec,
  const gchar* symbol_name,
  const gchar* message,
  gint is_error
)

Description [src]

Outputs a message through the scanner’s msg_handler, resulting from an unexpected token in the input stream. Note that you should not call g_scanner_peek_next_token() followed by g_scanner_unexp_token() without an intermediate call to g_scanner_get_next_token(), as g_scanner_unexp_token() evaluates the scanner’s current token (not the peeked token) to construct part of the message.

Parameters

expected_token

Type: GTokenType

The expected token.

identifier_spec

Type: const gchar*

A string describing how the scanner’s user refers to identifiers (NULL defaults to “identifier”). This is used if expected_token is G_TOKEN_IDENTIFIER or G_TOKEN_IDENTIFIER_NULL.

The data is owned by the caller of the method.
The value is a NUL terminated UTF-8 string.
symbol_spec

Type: const gchar*

A string describing how the scanner’s user refers to symbols (NULL defaults to “symbol”). This is used if expected_token is G_TOKEN_SYMBOL or any token value greater than G_TOKEN_LAST.

The data is owned by the caller of the method.
The value is a NUL terminated UTF-8 string.
symbol_name

Type: const gchar*

The name of the symbol, if the scanner’s current token is a symbol.

The data is owned by the caller of the method.
The value is a NUL terminated UTF-8 string.
message

Type: const gchar*

A message string to output at the end of the warning/error, or NULL.
