Field Details

sscanf

public static final long sscanf

The address of the sscanf function.

snprintf

public static final long snprintf

The address of the snprintf function.

Method Details

nvsscanf

public static int nvsscanf(long buffer,
 long format,
 long vlist)

Unsafe version of: vsscanf(java.nio.ByteBuffer, java.nio.ByteBuffer, long)

vsscanf

public static int vsscanf(ByteBuffer buffer,
 ByteBuffer format,
 long vlist)

Reads data from the null-terminated character string buffer, interprets it according to format and stores the results into locations defined by vlist.

Parameters:

buffer - pointer to a null-terminated character string to read from

format - pointer to a null-terminated character string specifying how to read the input

vlist - variable argument list containing the receiving arguments

Returns:

the number of receiving arguments successfully assigned, or EOF if read failure occurs before the first receiving argument was assigned

vsscanf

public static int vsscanf(CharSequence buffer,
 CharSequence format,
 long vlist)

Reads data from the null-terminated character string buffer, interprets it according to format and stores the results into locations defined by vlist.

Parameters:

buffer - pointer to a null-terminated character string to read from

format - pointer to a null-terminated character string specifying how to read the input

vlist - variable argument list containing the receiving arguments

Returns:

the number of receiving arguments successfully assigned, or EOF if read failure occurs before the first receiving argument was assigned

nvsnprintf

public static int nvsnprintf(long buffer,
 long buf_size,
 long format,
 long vlist)

Unsafe version of: vsnprintf(java.nio.ByteBuffer, java.nio.ByteBuffer, long)

Parameters:

buf_size - up to buf_size - 1 characters may be written, plus the null terminator

vsnprintf

public static int vsnprintf(@Nullable
 ByteBuffer buffer,
 ByteBuffer format,
 long vlist)

Loads the data from the locations, defined by vlist, converts them to character string equivalents and writes the results to a character string buffer.

Parameters:

buffer - pointer to a character string to write to

format - pointer to a null-terminated character string specifying how to interpret the data

vlist - variable argument list containing the data to print

Returns:

the number of characters written if successful or negative value if an error occurred. If the resulting string gets truncated due to buf_size limit, function returns the total number of characters (not including the terminating null-byte) which would have been written, if the limit was not imposed.

vsnprintf

public static int vsnprintf(@Nullable
 ByteBuffer buffer,
 CharSequence format,
 long vlist)

Loads the data from the locations, defined by vlist, converts them to character string equivalents and writes the results to a character string buffer.

Parameters:

buffer - pointer to a character string to write to

format - pointer to a null-terminated character string specifying how to interpret the data

vlist - variable argument list containing the data to print

Returns:

the number of characters written if successful or negative value if an error occurred. If the resulting string gets truncated due to buf_size limit, function returns the total number of characters (not including the terminating null-byte) which would have been written, if the limit was not imposed.
