char* nl_geterror ( void   ) 

Returns:
error message

Definition at line 142 of file utils.c.

Referenced by nl_perror().

void nl_perror ( const char *  s  ) 

Parameters:
s error message prefix
Prints the error message of the call that failed last.

If s is not NULL and *s is not a null byte the argument string is printed, followed by a colon and a blank. Then the error message and a new-line.

Definition at line 163 of file utils.c.

double nl_cancel_down_bytes ( unsigned long long  l,
char **  unit 
)

Parameters:
l byte counter
unit destination unit pointer
Cancels down a byte counter until it reaches a reasonable unit. The chosen unit is assigned to unit.

Returns:
The cancelled down byte counter in the new unit.

Definition at line 188 of file utils.c.

double nl_cancel_down_bits ( unsigned long long  l,
char **  unit 
)

Parameters:
l bit counter
unit destination unit pointer
Cancels downa bit counter until it reaches a reasonable unit. The chosen unit is assigned to unit.

Returns:
The cancelled down bit counter in the new unit.

Definition at line 218 of file utils.c.

double nl_cancel_down_us ( uint32_t  l,
char **  unit 
)

Parameters:
l micro seconds
unit destination unit pointer
Cancels down a microsecond counter until it reaches a reasonable unit. The chosen unit is assigned to unit.

Returns:
The cancelled down microsecond in the new unit

Definition at line 249 of file utils.c.

long nl_size2int ( const char *  str  ) 

Parameters:
str size encoded as character string
Converts the specified size as character to the corresponding number of bytes.

Supported formats are:

  • b,kb/k,m/mb,gb/g for bytes
  • bit,kbit/mbit/gbit

Returns:
The number of bytes or -1 if the string is unparseable

Definition at line 283 of file utils.c.

long nl_prob2int ( const char *  str  ) 

Parameters:
str probability encoded as character string
Converts the specified probability as character to the corresponding probability number.

Supported formats are:

  • 0.0-1.0
  • 0-100%

Returns:
The probability relative to NL_PROB_MIN and NL_PROB_MAX

Definition at line 325 of file utils.c.

References NL_PROB_MAX.

uint32_t nl_us2ticks ( uint32_t  us  ) 

Parameters:
us micro seconds
Returns:
number of ticks

uint32_t nl_ticks2us ( uint32_t  ticks  ) 

Parameters:
ticks number of ticks
Returns:
microseconds

char* nl_msec2str ( uint64_t  msec,
char *  buf,
size_t  len 
)

Parameters:
msec number of milliseconds
buf destination buffer
len buffer length
Converts milliseconds to a character string split up in days, hours, minutes, seconds, and milliseconds and stores it in the specified destination buffer.

Returns:
The destination buffer.

Definition at line 478 of file utils.c.

void nl_new_line ( struct nl_dump_params params,
int  line 
)

Parameters:
params Dumping parameters
line Number of lines dumped already.
This function must be called before dumping any onto a new line. It will ensure proper prefixing as specified by the dumping parameters.

Note:
This function will NOT dump any newlines itself

void nl_dump ( struct nl_dump_params params,
const char *  fmt,
  ... 
)

Parameters:
params Dumping parameters
fmt printf style formatting string
... Arguments to formatting string
Dumps a printf style formatting string to the output device as specified by the dumping parameters.
