H5PT_READ_PACKETS

Reads a number of packets from a packet table.

Procedure:

H5PT_READ_PACKETS(table_id, start, nrecords, data)

Signature:

herr_t H5PTread_packets(hid_t table_id, hsize_t start, size_t nrecords, void* data)

Parameters:

hid_t table_id

    IN: Identifier of packet table to read from.

hsize_t start

    IN: Packet to start reading from.

size_t nrecords

    IN: Number of packets to be read.

void * data

    OUT: Buffer into which to read data.

Description:

H5PTread_packets reads nrecords packets starting at packet number start from a packet table specified by table_id. data is a buffer into which the data should be read.

For a packet table holding variable-length records, the data returned in the buffer will be in form of hvl_t structs, each containing the length of the data and a pointer to it in memory. The memory used by this data must be freed using H5PTfree_vlen_buff.

Returns:

Returns a non-negative value if successful, otherwise returns a negative value.

Example:

int
main (void)
{
    hsize_t     dims[2], dimsm[2];   
    int         data[DIM0][DIM1];           /* data to write */
    int         sdata[DIM0_SUB][DIM1_SUB];  /* subset to write */
    int         rdata[DIM0][DIM1];          /* buffer for read */
 
    hid_t       file_id, dataset_id;        /* handles */
    hid_t       dataspace_id, memspace_id;
