NAME

       gd_put_carray, gd_put_carray_slice -- write CARRAY data to a dirfile database

SYNOPSIS

       #include <getdata.h>

       int gd_put_carray_slice(DIRFILE *dirfile, const char *field_code, unsigned int start, size_t len, gd_type_t data_type, const void
	      *data_in);

       int gd_put_carray(DIRFILE *dirfile, const char *field_code, gd_type_t data_type, const void *data_in);

DESCRIPTION

       The gd_put_carray_slice() function writes data to a dirfile(5) database specified by dirfile into the CARRAY scalar array field_code.   The
       data  in the field is converted from the data type specified by data_type, and read from in the user-supplied buffer data_in.  The location
       of the first element of the field into which data is stored is given by start, and the number of elements stored  is  given  by	len.   The
       gd_put_carray()	function  behaves  similarly,  except the whole scalar array is written.  These interface cannot write to field represeta-
       tions.

       The argument data_in must point to a valid memory location containing all the data to be written.  The number of  elements  which  will	be
       stored by gd_put_carray() may be obtained by calling gd_carray_len(3).  Unlike gd_putdata(3), writing data past the end of the field is not
       permitted.  To add data to the CARRAY, first increase its length by calling gd_alter_carray(3), or another equivalent function.

       The data_type argument should be one of the following symbols, which indicates the type of the data pointed to by data_in:

	      GD_UINT8	 unsigned 8-bit integer

	      GD_INT8	 signed (two's complement) 8-bit integer

	      GD_UINT16  unsigned 16-bit integer

	      GD_INT16	 signed (two's complement) 16-bit integer

	      GD_UINT32  unsigned 32-bit integer

	      GD_INT32	 signed (two's complement) 32-bit integer

	      GD_UINT64  unsigned 64-bit integer

	      GD_INT64	 signed (two's complement) 64-bit integer

	      GD_FLOAT32 IEEE-754 standard 32-bit single precision floating point number

	      GD_FLOAT64 IEEE-754 standard 64-bit double precision floating point number

	      GD_COMPLEX64
			 C99-conformant 64-bit single precision complex number

	      GD_COMPLEX128
			 C99-conformant 128-bit double precision complex number

       The type of the input data need not be the same as the CARRAY storage type.  Type conversion will be performed as necessary to  return  the
       requested type.	The dirfile argument must point to a valid DIRFILE object previously created by a call to gd_open(3).

RETURN VALUE

       On success, gd_put_carray() and gd_put_carray_slice() return zero.  On error, they return -1 and set the dirfile error to a non-zero value.
       Possible error values are:

       GD_E_ACCMODE
	       The specified dirfile was opened read-only.

       GD_E_BAD_CODE
	       The field specified by field_code was not found in the database.

       GD_E_BAD_DIRFILE
	       An invalid dirfile was supplied.

       GD_E_BAD_FIELD_TYPE
	       The supplied field_code referred to a field of a type other than CARRAY.  The caller should use gd_putdata(3),  gd_put_constant(3),
	       or gd_put_string(3) instead.

       GD_E_BAD_REPR
	       A  representation  suffix  in the field definition was invalid, or an attempt was made to write to a representation, instead of the
	       underlying field.

       GD_E_BAD_TYPE
	       An invalid data_type was specified.

       GE_E_BOUNDS
	       A request for data beyond the end of the field was made.

       GD_E_INTERNAL_ERROR
	       An internal error occurred in the library while trying to perform the task.  This indicates a bug in the  library.   Please  report
	       the incident to the maintainer.

       The  dirfile error may be retrieved by calling gd_error(3).  A descriptive error string for the last error encountered may be obtained from
       a call to gd_error_string(3).
