Starboard Module Reference: log.h

Defines debug logging functions.

Enums

SbLogPriority

The priority at which a message should be logged. The platform may be configured to filter logs by priority, or render them differently.

Values

  • kSbLogPriorityUnknown
  • kSbLogPriorityInfo
  • kSbLogPriorityWarning
  • kSbLogPriorityError
  • kSbLogPriorityFatal

Functions

SbLog

Writes message to the platform's debug output log.

priority: The SbLogPriority at which the message should be logged. Note that passing kSbLogPriorityFatal does not terminate the program. Such a policy must be enforced at the application level. In fact, priority may be completely ignored on many platforms. message: The message to be logged. No formatting is required to be done on the value, including newline termination. That said, platforms can adjust the message to be more suitable for their output method by wrapping the text, stripping unprintable characters, etc.

Declaration

void SbLog(SbLogPriority priority, const char *message)

SbLogFlush

Flushes the log buffer on some platforms.

Declaration

void SbLogFlush()

SbLogFormat

A log output method that additionally performs a string format on the data being logged.

Declaration

void SbLogFormat(const char *format, va_list args) SB_PRINTF_FORMAT(1

SbLogFormatF

Inline wrapper of SbLogFormat that converts from ellipsis to va_args.

Declaration

void static void void SbLogFormatF(const char *format,...) SB_PRINTF_FORMAT(1

SbLogIsTty

Indicates whether the log output goes to a TTY or is being redirected.

Declaration

bool SbLogIsTty()

SbLogRaw

A bare-bones log output method that is async-signal-safe, i.e. safe to call from an asynchronous signal handler (e.g. a SIGSEGV handler). It should not do any additional formatting.

message: The message to be logged.

Declaration

void SbLogRaw(const char *message)

SbLogRawDumpStack

Dumps the stack of the current thread to the log in an async-signal-safe manner, i.e. safe to call from an asynchronous signal handler (e.g. a SIGSEGV handler). Does not include SbLogRawDumpStack itself.

frames_to_skip: The number of frames to skip from the top of the stack when dumping the current thread to the log. This parameter lets you remove noise from helper functions that might end up on top of every stack dump so that the stack dump is just the relevant function stack where the problem occurred.

Declaration

void SbLogRawDumpStack(int frames_to_skip)

SbLogRawFormat

A formatted log output method that is async-signal-safe, i.e. safe to call from an asynchronous signal handler (e.g. a SIGSEGV handler).

Declaration

void SbLogRawFormat(const char *format, va_list args) SB_PRINTF_FORMAT(1

SbLogRawFormatF

Inline wrapper of SbLogFormat to convert from ellipsis to va_args.

Declaration

void static void void SbLogRawFormatF(const char *format,...) SB_PRINTF_FORMAT(1
