Description Jan Kümmel 2014-02-15 18:17:16 UTC 
g-ir-scanner (1.38.0) maps unsigned char* to guint8

I would have expected gpointer or something like that.

a header file containing the following line
void unsignedchar_test(unsigned char* data);

is transformed to this block:

    <function name="test" c:identifier="unsignedchar_test">
      <return-value transfer-ownership="none">
        <type name="none" c:type="void"/>
      </return-value>
      <parameters>
        <parameter name="data" transfer-ownership="none">
          <type name="guint8" c:type="unsigned char*"/>
        </parameter>
      </parameters>
    </function>
Comment 1 Simon Feltman 2014-08-20 02:29:37 UTC 
While it is obviously wrong, I'm not sure what should be expected. Is this an out argument or is it an input buffer? Either case can be annotated explicitly:

/**
 * test_unsignedchar:
 * @data: (out caller-allocates):
 **/

or

/**
 * test_unsignedchar:
 * @data: (array zero-terminated=1):
 **/

See: https://wiki.gnome.org/Projects/GObjectIntrospection/Annotations

If anything I think the scanner should probably generate an error and skip the method due to the ambiguity.
