## Enumeration Type Documentation

## ◆ Severity

enum fsdk::log::Severity

Log message severity enumeration.

Enumerator
SV_ERROR | Critical error.
SV_WARN | Recoverable error / non-critical issue.
SV_INFO | Generic information.
SV_DEBUG | Extended (debugging) information (verbose).
SV_DEFAULT | Default severity.

## Function Documentation

## ◆ getDefaultPrintFunction()

FSDK_API PrintFunction fsdk::log::getDefaultPrintFunction | ( |  | ) |
| noexcept

Get default print function pointer. Is thread-safe.

Returns
  print function pointer.

See also
  PrintFunction.

## ◆ getPrintFunction()

FSDK_API PrintFunction fsdk::log::getPrintFunction | ( |  | ) |
| noexcept

Get print function pointer.

Returns
  print function pointer.

See also
  PrintFunction.

## ◆ getSeverityFilter()

FSDK_API int fsdk::log::getSeverityFilter | ( |  | ) |
| noexcept

Get log severity filter.

Returns
  severity level.

See also
  Severity.

## ◆ restorePrintFunction()

FSDK_API void fsdk::log::restorePrintFunction | ( |  | ) |
| noexcept

Helper function to restore default print function. This is equivalent to:

setPrintFunction(getDefaultPrintFunction());

## ◆ setPrintFunction()

FSDK_API void fsdk::log::setPrintFunction | ( | PrintFunction | function | ) |
| noexcept

Set print function pointer. Default function is made thread-safe with function-local mutex. It means that if you provide your custom print function it's your duty to make it thread safe or not thread safe.

Parameters

  [in] | function | new function pointer.

See also
  PrintFunction. Any exception thrown out of param function is catched, but not throwing is better idea still.

## ◆ setSeverityFilter()

FSDK_API void fsdk::log::setSeverityFilter | ( | int | severity | ) |
| noexcept

Sets severity logging filter.

Parameters

  [in] | severity | desired severity filter.

  Severity.
