## AssignTimeT()

void crashpad::internal::MinidumpWriterUtil::AssignTimeT | ( | uint32_t * | destination,
|  | time_t | source
| ) |  |

static

Assigns a `time_t` value, logging a warning if the result overflows the destination buffer and will be truncated.

Parameters

  [out] | destination | A pointer to the variable to be assigned to.
  [in] | source | The value to assign.

The minidump format uses `uint32_t` for many timestamp values, but `time_t` may be wider than this. These year 2038 bugs are a limitation of the minidump format. An out-of-range error will be noted with a warning, but is not considered fatal. source will be truncated and assigned to destination in this case.

For `time_t` values with nonfatal overflow semantics, this function is used in preference to AssignIfInRange(), which fails without performing an assignment when an out-of-range condition is detected.

## AssignUTF8ToUTF16()

void crashpad::internal::MinidumpWriterUtil::AssignUTF8ToUTF16 | ( | base::char16 * | destination,
|  | size_t | destination_size,
|  | const std::string & | source
| ) |  |

static

Converts a UTF-8 string to UTF-16 and places it into a buffer of fixed size, taking care to `NUL`-terminate the buffer and not to overflow it. If the string will be truncated or if it cannot be converted losslessly, a warning is logged.

Any unused portion of the destination buffer that is not written to by the converted string will be overwritten with `NUL` UTF-16 code units, thus, this function always writes destination_size `char16` units.

If the conversion is lossy, U+FFFD “replacement characters” will be introduced.

Parameters

  [out] | destination | A pointer to the destination buffer, where the UTF-16-encoded string will be written.
  [in] | destination_size | The size of destination in `char16` units, including space used by a `NUL` terminator.
  [in] | source | The UTF-8-encoded input string.

## ConvertUTF8ToUTF16()

base::string16 crashpad::internal::MinidumpWriterUtil::ConvertUTF8ToUTF16 | ( | const std::string & | utf8 | ) |

static

Converts a UTF-8 string to UTF-16 and returns it. If the string cannot be converted losslessly, indicating that the input is not well-formed UTF-8, a warning is logged.

Parameters

  [in] | utf8 | The UTF-8-encoded string to convert.

Returns
  The utf8 string, converted to UTF-16 encoding. If the conversion is lossy, U+FFFD “replacement characters” will be introduced.
