Bug 566348 - g_file_open_tmp uses the wrong g_mkstemp on win32
2009-01-05 Tor Lillqvist <tml@iki.fi> Bug 566348 - g_file_open_tmp uses the wrong g_mkstemp on win32 * glib/gfileutils.c: Move the binary compatibility versions of g_file_test(), g_file_get_contents(), g_mkstemp() and g_file_open_tmp() last in the file. Remove the restriction that the XXXXXX is last in the template in the binary compatibility version of g_mkstemp(). Thanks to Morten Welinder and Jody Goldberg. svn path=/trunk/; revision=7770

Bug 566348 - g_file_open_tmp uses the wrong g_mkstemp on win32

* glib/gfileutils.c: Move the binary compatibility versions of

g_file_test(), g_file_get_contents(), g_mkstemp() and

g_file_open_tmp() last in the file. Remove the restriction that
|

the XXXXXX is last in the template in the binary compatibility
|
||||
version of g_mkstemp(). Thanks to Morten Welinder and Jody
