CommandLineArgumentToFilePathStringType()

base::FilePath::StringType crashpad::ToolSupport::CommandLineArgumentToFilePathStringType ( const base::StringPiece &  arg )

static

Converts a command line argument to the string type suitable for base::FilePath.

On POSIX, this is a no-op. On Windows, assumes that Wmain() was used, and the input argument was converted from UTF-16 in a wchar_t* to UTF-8 in a char*. This undoes that transformation.

Wmain()

FilePathToCommandLineArgument()

FilePathToCommandLineArgument()

std::string crashpad::ToolSupport::FilePathToCommandLineArgument ( const base::FilePath &  file_path )

static

Converts a base::FilePath to a command line argument.

On POSIX, this is a no-op. On Windows, this undoes the transformation done by CommandLineArgumentToFilePathStringType() in the same manner as Wmain().

UsageHint() [1/2]

void crashpad::ToolSupport::UsageHint ( const base::FilePath &  me, const char *  hint  )

static

Suggests using --help when a command line tool can’t make sense of its arguments.

Parameters

[in]	me	The tool’s name, the basename of argv[0].
[in]	hint	A hint to display before the suggestion to try --help. Optional, may be nullptr, in which case no hint will be presented.

UsageHint() [2/2]

static void crashpad::ToolSupport::UsageHint ( const std::string &  me, const char *  hint  )

static

Suggests using --help when a command line tool can’t make sense of its arguments.

Parameters

[in]	me	The tool’s name, the basename of argv[0].
[in]	hint	A hint to display before the suggestion to try --help. Optional, may be nullptr, in which case no hint will be presented.

UsageTail() [1/2]

void crashpad::ToolSupport::UsageTail ( const base::FilePath &  me )

static

Prints the footer for --help.

Parameters

[in]

me

The tool’s name, the basename of argv[0].

UsageTail() [2/2]

static void crashpad::ToolSupport::UsageTail ( const std::string &  me )

static

Prints the footer for --help.

Parameters

[in]

me

The tool’s name, the basename of argv[0].

Version() [1/2]

void crashpad::ToolSupport::Version ( const base::FilePath &  me )

static

Handles --version.

Parameters

[in]

me

The tool’s name, the basename of argv[0].

Version() [2/2]

static void crashpad::ToolSupport::Version ( const std::string &  me )

static

Handles --version.

Parameters

[in]

me

The tool’s name, the basename of argv[0].

Wmain()

static int crashpad::ToolSupport::Wmain ( int  argc, wchar_t *  argv[], int(*)(int, char *[])  entry  )

static

Converts argv wchar_t UTF-16 to UTF-8, and passes onwards to a UTF-8 entry point.

Returns

The return value of entry.
