gd_carray_len(3)		    GETDATA		      gd_carray_len(3)

NAME
       gd_carray_len — returns the length of a CARRAY field in a dirfile

SYNOPSIS
       #include <getdata.h>

       size_t gd_carray_len(DIRFILE *dirfile, const char *field_code);

DESCRIPTION
       The gd_carray_len() function queries a dirfile(5) database specified by
       dirfile and returns the number of length of the CONST or	 CARRAY	 field
       field_code.   If	 field_code contains a valid representation suffix, it
       will be ignored.

       The dirfile argument must point to a valid  DIRFILE  object  previously
       created by a call to gd_open(3).

RETURN VALUE
       Upon successful completion, gd_carray_len() returns the array length of
       the field specified.  (The length of a CONST field is  always  1.)   On
       error,  it  returns zero and sets the dirfile error to a non-zero error
       value.  Possible error values are:

       GD_E_ALLOC
	       The library was unable to allocate memory.

       GD_E_BAD_CODE
	       The field specified by field_code was not found	in  the	 data‐
	       base.

       GD_E_BAD_DIRFILE
	       The supplied dirfile was invalid.

       GD_E_BAD_FIELD_TYPE
	       The field specified by field_code was not a CONST or CARRAY.

       GD_E_BAD_REPR
	       The  representation  suffix  specified  in  field_code  was not
	       recognised.

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