25 /* NEVER include any captive/reactos include file as we are included
26 * from libcaptive/ke/exports.c which conflicts on any export symbol declaration.
33 * captive_kernel_exports:
35 * Export complete libcaptive modules to reactos. It is done by *.def files used
36 * by dlltool(1) of Mingw32 compiler suite. We use native host OS compiler and
37 * we also have just a limited set of functions over reactos itself.
38 * We use our captive_ModuleList_add_builtin() to simulate PE headers exporting
39 * our symbols; this export simulation is invocated from this function.
41 * This function is generated automatically from #exports.captivesym file
42 * by #captivesym.pl script.
44 * Multiple calls of this function are forbidden. See also captive_kernel_patches().
46 * Returns: %TRUE if the export was successful.
48 gboolean captive_kernel_exports(void);
52 * captive_kernel_patches_debug:
54 * Patches W32 libraries by libcaptive functions. It is done by *.def files used
55 * by dlltool(1) of Mingw32 compiler suite. We use native host OS compiler and
56 * we also have just a limited set of functions over reactos itself.
57 * We use our captive_ModuleList_patch() to modify existing module function
58 * tables generated from captive_ModuleList_add_builtin().
60 * This function is generated automatically from #exports.captivesym file
61 * by #captivesym.pl script.
63 * This function is used in --debug-messages mode as it also patches 'pass'
64 * functions to be successfuly debug dumped.
66 * Multiple calls of this function are forbidden. See also captive_kernel_exports().
68 * Returns: %TRUE if the export was successful.
70 gboolean captive_kernel_patches_debug(void);
74 * captive_kernel_patches_nondebug:
76 * Function equivalent to captive_kernel_patches_debug() but it does not patch
77 * 'pass' functions as they are not needed to be traced if no --debug-messages
78 * was specified. See captive_kernel_patches_debug() for the description
81 * Returns: %TRUE if the export was successful.
