long nl_size2int | ( | const char * | str | ) |
Convert a character string to a size.
str | size encoded as character string |
Converts the specified size as character to the corresponding number of bytes.
Supported formats are:
char* nl_size2str | ( | const size_t | size, | |
char * | buf, | |||
const size_t | len | |||
) |
Convert a size toa character string.
size | Size in number of bytes | |
buf | Buffer to write character string to | |
len | Size of buf |
This function converts a value in bytes to a human readable representation of it. The function uses IEC prefixes:
1024 bytes => 1 KiB 1048576 bytes => 1 MiB
The highest prefix is used which ensures a result of >= 1.0, the result is provided as floating point number with a maximum precision of 2 digits:
965176 bytes => 942.55 KiB
long nl_prob2int | ( | const char * | str | ) |
Convert a character string to a probability.
str | probability encoded as character string |
Converts the specified probability as character to the corresponding probability number.

char* nl_msec2str | ( | uint64_t | msec, | |
char * | buf, | |||
size_t | len | |||
) |
Convert milliseconds to a character string.
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.
void nl_new_line | ( | struct nl_dump_params * | params | ) |
Handle a new line while dumping.
params | Dumping parameters |
This function must be called before dumping any onto a new line. It will ensure proper prefixing as specified by the dumping parameters.
