NAME¶
gd_put_carray, gd_put_carray_slice — write CARRAY data to a dirfile databaseSYNOPSIS¶
#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 represetations.- GD_UINT8

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.
