@deftypefun {int} {gnutls_hex2bin} (const char * @var{hex_data}, size_t @var{hex_size}, void * @var{bin_data}, size_t * @var{bin_size})
@var{hex_data}: string with data in hex format

@var{hex_size}: size of hex data

@var{bin_data}: output array with binary data

@var{bin_size}: when calling should hold maximum size of  @code{bin_data} ,
on return will hold actual length of  @code{bin_data} .

Convert a buffer with hex data to binary data. This function
unlike @code{gnutls_hex_decode()}  can parse hex data with separators
between numbers. That is, it ignores any non-hex characters.

@strong{Returns:} @code{GNUTLS_E_SUCCESS}  on success, otherwise a negative error code.

@strong{Since:} 2.4.0
