Function Documentation

int NI_base64_to_val NI_stream_type   ns,
NI_rowtype   rt,
void *    dpt,
int    swap
 

Decode Base64 data from the NI_stream ns into a rowtype struct *dpt.

  • Note that String (aka NI_STRING) parts are illegal here.
  • Return value is 1 if all was OK, 0 if something bad happened.
  • Parameter swap indicates that the data coming in needs to be byte-swapped.
    • This is ONLY used to byte-swap the dimension for var-dimen arrays.
    • Actual byte-swapping of the data is done in NI_swap_column(). ---------------------------------------------------------------------------

int *    col_typ,

void **    col_dpt,
int    tmode,
int    flags
 

Read "columns" of data from a NI_stream. Each column is an array of structs of some NI_rowtype (including the builtin types):

  • ns = stream to read from
  • col_num = number of columns to read (1,2,...)
  • col_typ[i] = type code for column i (i=0..col_num-1)
  • col_len = number of elements in each column
    • col_len can be 0, which means read data until the end-of-input
    • end-of-input is end-of-stream, or '<' in NI_TEXT_MODE
  • col_dpt[i] = pointer to data in column i
    • col_dpt can't be NULL
    • but if col_dpt[i] is NULL, it will be NI_malloc()-ed
    • if col_dpt[i] isn't NULL, it must point to space big enough to hold the input (col_num * fixed size of rowtype i)
    • if col_len==0 on input:
      • then col_dpt[i] should be NULL for i=0..col_num-1
      • this function will NI_malloc() to fit the amount of data scanned
      • if col_dpt[i]!=NULL with col_len==0, then function returns -1
  • tmode is one of
    • NI_TEXT_MODE ==> ASCII input
      • text mode is required if any rowtype component is a String
      • text mode is required from "str:" streams
    • NI_BINARY_MODE ==> binary input
    • NI_BASE64_MODE ==> binary/base64 input
  • flags is the OR of various bit masks
    • NI_SWAP_MASK ==> binary input must be byte-swapped after input
    • NI_LTEND_MASK ==> text input stops at a '<' in the input
  • return value is:
    • number of complete rows actually read (<= col_len)
    • zero if stream isn't ready to read
    • -1 if something bad happened
Only the data is read from the stream - no header or footer. This function is adapted from the 1st edition of NI_read_element(). --------------------------------------------------------------------------

int NI_write_columns NI_stream_type   ns,
int    col_num,
int *    col_typ,
int    col_len,
void **    col_dpt,
int    tmode
 

Write "columns" of data to a NI_stream. Each column is an array of structs of some NI_rowtype (including the builtin types):

  • ns = stream to write to
  • col_num = number of columns to write (1,2,...)
  • col_typ[i] = type code for column i (i=0..col_num-1)
  • col_len = number of elements in each column
  • col_dpt[i] = pointer to data in column i
  • tmode is one of
    • NI_TEXT_MODE ==> ASCII output
      • text mode is required if any data component is a String
      • text mode is required to "str:" streams
    • NI_BINARY_MODE ==> binary output (endian-ness of this CPU)
    • NI_BASE64_MODE ==> binary/base64 output (ditto)
  • return value is number of bytes written to stream (-1 if something bad happened, 0 if can't write to stream yet)
Only the data is written to the stream - no header or footer. This function is adapted from the 1st edition of NI_write_element(). --------------------------------------------------------------------------
