ErrorReactionInternal sys_display_error	(	const wchar_t *	text,
		size_t	flags
	)

show the error dialog.

Parameters

text	to display (practically unlimited length)
flags,:	see DebugDisplayErrorFlags.

Returns: ErrorReactionInternal (except ERI_EXIT, which is acted on immediately)

called from debug_DisplayError unless overridden by means of ah_display_error.

Definition at line 284 of file wsysdep.cpp.

void sys_display_msg	(	const wchar_t *	caption,
		const wchar_t *	msg
	)

display a message.

Parameters

caption	title message
msg	message contents

implemented as a MessageBox on Win32 and printf on Unix. called from debug_DisplayMessage.

Definition at line 76 of file wsysdep.cpp.

OsPath sys_ExecutablePathname ( )

Returns: full pathname of the current executable.

this is useful for determining installation directory, e.g. for VFS.

Definition at line 395 of file wsysdep.cpp.

Status sys_generate_random_bytes	(	u8 *	buf,
		size_t	count
	)

generate high-quality random bytes.

this should only be used with small numbers of bytes, to avoid hogging the system's entropy.

Definition at line 476 of file wsysdep.cpp.

Status sys_get_module_filename	(	void *	addr,
		OsPath &	pathname
	)

determine filename of the module to whom an address belongs.

Parameters

addr
pathname	Full path to module (unchanged unless INFO::OK is returned).

Returns: Status

note: this is useful for handling exceptions in other modules.

Definition at line 384 of file wsysdep.cpp.

std::wstring sys_get_user_name ( )

Get the current user's login name.

Returns: login name, or empty string on error

Definition at line 404 of file wsysdep.cpp.

bool sys_IsDebuggerPresent ( )

Returns: whether a debugger is attached to the process (if so, it is safe to use debug_break; otherwise, that would raise an exception)

Definition at line 53 of file wsysdep.cpp.

Status sys_open_url ( const std::string & url )

Open the user's default web browser to the given URL.

Definition at line 466 of file wsysdep.cpp.

FILE* sys_OpenFile	(	const OsPath &	pathname,
		const char *	mode
	)

open a file like with fopen (but taking an OsPath argument).

Definition at line 606 of file wsysdep.cpp.

Status sys_pick_directory ( OsPath & path )

Have the user choose a directory via OS dialog.

Parameters

path	Path's input value determines the starting directory for faster browsing. if INFO::OK is returned, it receives chosen directory path.

Definition at line 428 of file wsysdep.cpp.

Status sys_StatusDescription	(	int	err,
		wchar_t *	buf,
		size_t	max_chars
	)

describe the current OS error state.

Parameters

err,:	if not 0, use that as the error code to translate; otherwise, uses GetLastError or similar.
buf	output buffer
max_chars	rationale: it is expected to be rare that OS return/error codes are actually seen by user code, but we leave the possibility open.

Definition at line 334 of file wsysdep.cpp.

std::wstring sys_WideFromArgv ( const char * argv_i )

Returns: a wide string conversion of the platform's encoding of main's argv.

(NB: wseh.cpp defines a wmain that converts argv to UTF-8 and calls main(), but only if LIB_STATIC_LINK)
