[][src]Function ffmpeg_sys_next::av_hash_final_hex

pub unsafe extern "C" fn av_hash_final_hex(
    ctx: *mut AVHashContext,
    dst: *mut u8,
    size: c_int
)

Finalize a hash context and store the hexadecimal representation of the actual hash value as a string.

It is not safe to update or finalize a hash context again, if it has already been finalized.

The string is always 0-terminated.

If size is smaller than 2 * hash_size + 1, where hash_size is the value returned by av_hash_get_size(), the string will be truncated.

@param[in,out] ctx Hash context @param[out] dst Where the string will be stored @param[in] size Maximum number of bytes to write to dst
