GLib.Variant.parse_error_print_context
Description: Reference for GLib.Variant.parse_error_print_context

### Function

# GLib Variantparse_error_print_context

since: 2.40

#### Declaration

    gchar*
    g_variant_parse_error_print_context (
      GError* error,
      const gchar* source_str
    )

#### Description

Pretty-prints a message showing the context of a `GVariant` parse error within the string for which parsing was attempted.

The resulting string is suitable for output to the console or other monospace media where newlines are treated in the usual way.

The message will typically look something like one of the following:

    unterminated string constant:
      (1, 2, 3, 'abc
                ^^^^

or

    unable to find a common type:
      [1, 2, 3, 'str']
       ^        ^^^^^

The format of the message may change in a future version.

`error` must have come from a failed attempt to `g_variant_parse()` and `source_str` must be exactly the same string that caused the error. If `source_str` was not nul-terminated when you passed it to `g_variant_parse()` then you must add nul termination before using this function.
