Detailed Description

Logger API for SoapySDR devices. Implementations should use the logger rather than stdio. The default log handler prints to stderr.

Macro Definition Documentation

#define SOAPY_SDR_SSI   SOAPY_SDR_SSI

Compile-time detection macro for SSI feature.

Typedef Documentation

typedef void(* SoapySDRLogHandler) (const SoapySDRLogLevel logLevel, const char *message)

Typedef for the registered log handler function.

Enumeration Type Documentation

The available priority levels for log messages.

The default log level threshold is SOAPY_SDR_INFO. Log messages with lower priorities are dropped.

The default threshold can be set via the SOAPY_SDR_LOG_LEVEL environment variable. Set SOAPY_SDR_LOG_LEVEL to the string value: "WARNING", "ERROR", "DEBUG", etc... or set it to the equivalent integer value.

Enumerator
SOAPY_SDR_FATAL 

A fatal error. The application will most likely terminate. This is the highest priority.

SOAPY_SDR_CRITICAL 

A critical error. The application might not be able to continue running successfully.

SOAPY_SDR_ERROR 

An error. An operation did not complete successfully, but the application as a whole is not affected.

SOAPY_SDR_WARNING 

A warning. An operation completed with an unexpected result.

SOAPY_SDR_NOTICE 

A notice, which is an information with just a higher priority.

SOAPY_SDR_INFO 

An informational message, usually denoting the successful completion of an operation.

SOAPY_SDR_DEBUG 

A debugging message.

SOAPY_SDR_TRACE 

A tracing message. This is the lowest priority.

SOAPY_SDR_SSI 

Streaming status indicators such as "U" (underflow) and "O" (overflow).

Function Documentation

SOAPY_SDR_API void SoapySDR_log ( const SoapySDRLogLevel  logLevel,
const char *  message 
)

Send a message to the registered logger.

Parameters
logLevela possible logging level
messagea logger message string
static void SoapySDR_logf ( const SoapySDRLogLevel  logLevel,
const char *  format,
  ... 
)
inlinestatic

Send a message to the registered logger.

Parameters
logLevela possible logging level
formata printf style format string
SOAPY_SDR_API void SoapySDR_registerLogHandler ( const SoapySDRLogHandler  handler)

Register a new system log handler. Platforms should call this to replace the default stdio handler.

SOAPY_SDR_API void SoapySDR_setLogLevel ( const SoapySDRLogLevel  logLevel)

Set the log level threshold. Log messages with lower priority are dropped.

SOAPY_SDR_API void SoapySDR_vlogf ( const SoapySDRLogLevel  logLevel,
const char *  format,
va_list  argList 
)

Send a message to the registered logger.

Parameters
logLevela possible logging level
formata printf style format string
argListan argument list for the formatter
