NAME
     getptabent, addptabent, endptabent, setptabent, numbptabent
     - get partition table file entry

SYNOPSIS
     #include <stdio.h>
     #include <apple/ptabent.h>

     struct ptabent *getptabent(filep)
     FILE *filep;

     int addptabent(filep, ptab)
     FILE *filep;
     struct ptabent *ptab;

     int endptabent(filep)
     FILE *filep;

     FILE *setptabent(fname, type)
     char *fname;
     char *type;

     int numptabent(filep)
     FILE *filep;

DESCRIPTION
     setptabent opens a partition table file and returns a file
     pointer which can then be used with getptabent or
     addptabent.  The type argument is the same as in fopen(3).
     getptabent returns a pointer to an object with the following
     structure containing the broken-out fields of a line in the
     partition table file.  The fields have meanings described in
     ptab(4).

        struct ptabent {
               char *ptab_name;    /* partition name */
               char *ptab_type;    /* partition type */
               int  ptab_ctrl;     /* controller number */
               int  ptab_disk;     /* disk number */
               int  ptab_part;     /* partition number */
        };

     addptabent adds the ptabent structure ptab to the end of the
     open file filep.  numptabent returns the number of partition
     table file entries and has the effect of rewinding the
     partition table file to allow repeated searches.
     endptabtent closes the file.

FILES
     /etc/ptab
STATUS MESSAGES AND VALUES
     A null pointer (0) is returned on EOF or error by setptabent
     and getptabent.  addptabent, endptabent, and numbptabent
     return EOF on error.
LIMITATIONS
     The returned ptabent structure points to static information
     that is overwritten in each call.
