Typedef Documentation

nanosecT

typedef uint32_t flatlogs::nanosecT

The type used for nanoseconds.

Rationale: unsigned 32 bits gives >4x10^9 nanoseconds, so enough for 1x10^9 nanoseconds.

Function Documentation

logLevelFromString()

logPrioT flatlogs::logLevelFromString

(

const std::string &

str

)

Get the log priority from a string, which might have the number or the name.

Evaluates the input string to find the closest match to the log level names. If the first non-whitespace character is a digit, then the string is treated as an integer and converted. If the first non-whitespace character is not a digit, then the string is converted to upper case and the log level is determined using the minimum number of characters. That is

• EM = EMERGENCY
• A = ALERT
• C = CRITICAL
• ER = ERROR
• W = WARNING
• N = NOTICE
• I = INFO, returns 3
• D, D1, DBG, DBG1, DEBUG = DEBUG
• D2, DBG2, DEBUG2 = DEBUG2
• DEF = DEFAULT

Returns

the log priority value if parsing is successful.

logPrio::LOG_UNKNOWN if parsing is not successful.
