gd_nvectors(3)							      GETDATA							    gd_nvectors(3)

NAME

       gd_nvectors -- report the number of vector fields in a dirfile

SYNOPSIS

       #include <getdata.h>

       unsigned int gd_nvectors(DIRFILE *dirfile);

DESCRIPTION

       The  gd_nvectors() function queries a dirfile(5) database specified by dirfile and returns the number of vector fields defined in the data-
       base (i.e.  fields of types BIT, LINCOM, LINTERP, MULTIPLY, PHASE, POLYNOM, RAW, SBIT).	Notably, this count does not include /META fields.

       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_nvectors() returns the number of vector fields in the dirfile.  On error,  it  returns  zero  and  sets  the
       dirfile error to a non-zero error value.  Possible error values are:

       GD_E_BAD_DIRFILE
	       The supplied dirfile was invalid.

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

NAME

       gd_nfields_by_type -- report the number of fields of a given type in a dirfile

SYNOPSIS

       #include <getdata.h>

       unsigned int gd_nfields_by_type(DIRFILE *dirfile, gd_entype_t type);

DESCRIPTION

       The  gd_nfields_by_type() function queries a dirfile(5) database specified by dirfile and returns the number of fields of type type defined
       in the database.  Notably, this count does not include /META fields.

       The dirfile argument must point to a valid DIRFILE object previously created by a call to gd_open(3).  The type argument should be  one	of
       the following symbols indicating the type of field to count:

	      GD_BIT_ENTRY, GD_CARRAY_ENTRY, GD_CONST_ENTRY, GD_DIVIDE_ENTRY, GD_INDEX_ENTRY, GD_LINCOM_ENTRY, GD_LINTERP_ENTRY,
	      GD_MULTIPLY_ENTRY, GD_PHASE_ENTRY, GD_POLYNOM_ENTRY, GD_RAW_ENTRY, GD_RECIP_ENTRY, GD_SBIT_ENTRY, GD_STRING_ENTRY.

RETURN VALUE

       Upon successful completion, gd_nfields_by_type() returns the number of defined fields in the dirfile.  On error, it returns zero  and  sets
       the dirfile error to a non-zero error value.  Possible error values are:

       GD_E_BAD_DIRFILE
	       The supplied dirfile was invalid.

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