fxfer.h File


Contains the fxc and fxs data structures for the C file-transfer functions.


The /usr/include/fxfer.h file defines the C program interface fxc structure for the fxfer file-transfer function. The Xfer parameter of the fxfer function specifies a pointer to the fxc structure. Each C program module that uses the fxfer function must include the fxfer.h file. The structures are for use with the C program interface to the HCON file-transfer program.

The C program interface fxc structure is defined as follows:

struct fxc {
   char *fxc_src;             /* Source file name               */
   int srclength;             /* Put here for Pascal stringptr  */
   char *fxc_dst;             /* Destination file name          */
   int dstlength;             /* Put here for Pascal stringptr  */
   struct fxcf {
      int   f_flags;          /* Option flags                   */
#define FXC_UP     0x0001

#define FXC_TRACKS   -1          /* Tracks                       */

      } f_s;
      char *f_aix_codepg;   /* Override default AIX codeset name*/
      int codepglength;     /* Put here for Pascal stringptr */
   } fxc_opts;
struct fxs {
   int  fxs_bytcnt;          /* Byte count                      */
   char *fxs_src;            /* Source file name                */
   int  srclen;              /* Put here for Pascal stringptr   */
   char *fxs_dst;            /* Destination file name           */
   int  dstlen;              /* Put here for Pascal stringptr   */
   char *fxs_ctime;          /* Destination file creation time  */
   int  timelen;             /* Put here for Pascal stringptr   */
   int  fxs_stat;            /* Status code                     */
   int  fxs_errno;           /* Errno                           */
struct fxp {
   char *prof_id;            /* Profile id                      */
   int  proflen;             /* Put here for Pascal stringptr   */
Note: The integer length values are placed within the /usr/include/fxfer.h file to allow for the direct conversion of a Pascal stringptr to a C program character pointer value. The integer value specifies the actual length of the string as defined in Pascal.

Implementation Specifics

The fxfer.h file is part of the Host Connection Program (HCON).

This file requires the use of a C compiler.
