ESQL/C library functions that use an LO file descriptor

The following table shows the HCL OneDB™ ESQL/C library functions that access the LO file descriptor.

ESQL/C library function	Purpose	See
ifx_lo_close()	Closes the smart large object that the LO file descriptor identifies and deallocates the LO file descriptor	The ifx_lo_close() function
ifx_lo_copy_to_lo()	Copies an operating-system file to an open smart large object that the LO file descriptor identifies	The ifx_lo_copy_to_lo() function
ifx_lo_create()	Creates and opens a new smart large object and returns an LO file descriptor	The ifx_lo_create() function
ifx_lo_open()	Opens a smart large object and returns an LO file descriptor	The ifx_lo_open() function
ifx_lo_read()	Reads data from the open smart large object that the LO file descriptor identifies	The ifx_lo_read() function
ifx_lo_readwithseek()	Seeks a specified file position in the open smart large object that the LO file descriptor identifies and then reads data from this position	The ifx_lo_readwithseek() function
ifx_lo_seek()	Moves the file position in the open smart large object that the LO file descriptor identifies	The ifx_lo_seek() function
ifx_lo_stat()	Obtains status information for the open smart large object that the LO file descriptor identifies	The ifx_lo_stat() function
ifx_lo_tell()	Determines the current file position in the open smart large object that the LO file descriptor identifies	The ifx_lo_tell() function
ifx_lo_truncate()	Truncates at a specified offset the open smart large object that the LO file descriptor identifies	The ifx_lo_truncate() function
ifx_lo_write()	Writes data to the open smart large object that the LO file descriptor identifies	The ifx_lo_write() function
ifx_lo_writewithseek()	Seeks a specified file position in the open smart large object that the LO file descriptor identifies and then writes data to this position	The ifx_lo_writewithseek() function
