Method

VarlinkMessageReaderpeek_string

Declaration [src]

const char*
varlink_message_reader_peek_string (
  VarlinkMessageReader* reader,
  gsize* length,
  GError** error
)

Description [src]

Borrows the current node as an unescaped UTF-8 string.

The returned data is borrowed from the underlying VarlinkMessage and is valid until reader is cleared or freed. It is not NUL-terminated; callers must use length. Escaped JSON strings cannot be borrowed because they need unescaping; use varlink_message_reader_dup_string() when a NUL-terminated string is required.

Parameters

length

Type: gsize*

Return location for the string length, in bytes.

The argument will be set by the function.
The argument can be NULL.
error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.
If the return location is not NULL, then you must initialize it to a NULL GError*.
The argument will be left initialized to NULL by the method if there are no errors.
In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: An array of guint8

borrowed UTF-8 bytes.

The length of the array is in the length argument.
The returned data is owned by the instance.
The return value can be NULL.
