◆ FTYPE_LOOKUP

#define FTYPE_LOOKUP	(	ftype,
		result
	)

Value:

    /* Check input */           \
    ws_assert(ftype < FT_NUM_TYPES);    \
    result = type_list[ftype];

Function Documentation

◆ byte_array_from_charconst()

GByteArray * byte_array_from_charconst	(	unsigned long	num,
		char **	err_msg
	)

Convert an unsigned long to a byte array.

Parameters

num	The number to convert.
err_msg	Pointer to store error message if conversion fails.

Returns: A new GByteArray containing the byte representation of num, or NULL on failure.

◆ byte_array_from_literal()

GByteArray * byte_array_from_literal	(	const char *	s,
		char **	err_msg
	)

Convert a literal string to a GByteArray.

This function takes a literal string and converts it into a GByteArray. Leading colons are skipped, and special cases for one-byte hex literals are handled.

Parameters

s	The input literal string.
err_msg	Pointer to store error message if any.

Returns: A new GByteArray or NULL on failure.

◆ bytes_to_dfilter_repr()

char * bytes_to_dfilter_repr	(	wmem_allocator_t *	scope,
		const uint8_t *	src,
		size_t	src_size
	)

Convert bytes to a string representation suitable for display filters.

This function converts an array of bytes into a hexadecimal string with punctuation, which can be used in display filters.

Parameters

scope	Memory allocation scope.
src	Pointer to the source byte array.
src_size	Size of the source byte array.

Returns: A newly allocated string representing the bytes, or NULL on failure.
