NAME

       cl_hp_unfold_field - Unfold header field

SYNOPSIS

       #include <libcanlock-3/canlock-hp.h>

       char *cl_hp_unfold_field(const char *data, size_t *data_len);

DESCRIPTION

       The cl_hp_unfold_field() function unfolds a header field.

       The parameter data should point to the beginning of the input data.
       Specify the length of the input data with the value pointed to by the data_len parameter.

       RFC 5322 specifies in Section 2.2 that CR and LF control characters in header field bodies
       are allowed for folding use only.  This function removes all CR and LF control  characters
       from the input data.

RETURN VALUE

       Upon successful completion a pointer to a new memory block, containing the unfolded header
       field with NUL-termination, is returned. Otherwise, NULL is returned.

       On success, the caller is responsible to free() the memory block allocated for the  output
       data.

       On  success  the  value  pointed  to  by data_len is updated to the length of the unfolded
       header field (without NUL-termination).
