◆ bytes_be_to_uint()

unsigned bytes_be_to_uint ( const unsigned char *  bytes)

Packs 4 big endian bytes into an unsigned.

Parameters
bytesPointer to an array of bytes that will be packed.
Returns
The packed unsigned.
Remarks
Assumes the passed array is least 4 bytes in size.
Assumes unsigned is 4 bytes in size.

◆ net_addr_from_str()

int net_addr_from_str ( NETADDR addr,
const char *  string 
)

Turns string into a network address.

Parameters
addrAddress to fill in.
stringString to parse.
Returns
0 on success

◆ net_addr_from_url()

int net_addr_from_url ( NETADDR addr,
const char *  string,
char *  host_buf,
size_t  host_buf_size 
)

Turns url string into a network address struct. The url format is tw-0.6+udp://{ipaddr}[:{port}] ipaddr: can be ipv4 or ipv6 port: is a optional internet protocol port

This format is used for parsing the master server, be careful before changing it.

Examples: tw-0.6+udp://127.0.0.1 tw-0.6+udp://127.0.0.1:8303

Parameters
addrAddress to fill in.
stringString to parse.
host_bufPointer to a buffer to write the host to It will include the port if one is included in the url It can also be set to NULL then it will be ignored
host_buf_sizeSize of the host buffer or 0 if no host_buf pointer is given
Returns
0 on success, positive if the input wasn't a valid DDNet URL, negative if the input is a valid DDNet URL but the host part was not a valid IPv4/IPv6 address

◆ str_utf8_offset_bytes_to_chars()

size_t str_utf8_offset_bytes_to_chars ( const char *  str,

Converts a byte offset of a utf8 string to the utf8 character offset.

Parameters
textPointer to the string.
byte_offsetOffset in bytes.
Returns
Offset in utf8 characters. Clamped to the maximum length of the string in utf8 characters.
Remarks
The string is treated as a zero-terminated utf8 string.
It's the user's responsibility to make sure the bounds are aligned.

Converts a utf8 character offset of a utf8 string to the byte offset.

Parameters
textPointer to the string.
char_offsetOffset in utf8 characters.
Returns
Offset in bytes. Clamped to the maximum length of the string in bytes.
Remarks
The string is treated as a zero-terminated utf8 string.
It's the user's responsibility to make sure the bounds are aligned.

◆ swap_endian()

void swap_endian ( void *  data,
unsigned  elem_size,

)

Swaps the endianness of data. Each element is swapped individually by reversing its bytes.

Parameters
dataPointer to data to be swapped.
elem_sizeSize in bytes of each element.
numNumber of elements.
Remarks
The caller must ensure that the data is at least elem_size * num bytes in size.

◆ timestamp_from_str()

bool timestamp_from_str ( const char *  string,
const char *  format,
time_t *  timestamp 
)

Parses a string into a timestamp following a specified format.

Parameters
stringPointer to the string to parse
formatThe time format to use (for example FORMAT_NOSPACE below)
timestampPointer to the timestamp result
Returns
true on success, false if the string could not be parsed with the specified format

◆ uint_to_bytes_be()

void uint_to_bytes_be ( unsigned char *  bytes,
unsigned  value

Packs an unsigned into 4 big endian bytes.

Parameters
bytesPointer to an array where the bytes will be stored.
valueThe values that will be packed into the array.
Remarks
Assumes the passed array is least 4 bytes in size.
Assumes unsigned is 4 bytes in size.
