ea_open(3exacct)

Extended Accounting File Access Library Functions             ea_open(3EXACCT)



NAME
       ea_open, ea_close - open or close exacct files

SYNOPSIS
       cc [ flag... ] file... -lexacct [ library... ]
       #include <exacct.h>

       int ea_open(ea_file_t *ef, char *name, char *creator, int aflags,
            int oflags, mode_t mode);


       int ea_close(ea_file_t *ef);

DESCRIPTION
       The  ea_open() function provides structured access to exacct files. The
       aflags argument contains the  appropriate  exacct  flags  necessary  to
       describe  the file. The oflags and mode arguments contain the appropri‐
       ate flags and mode to open the file; see  <fcntl.h>.  If  ea_open()  is
       invoked  with EO_HEAD specified in aflags, the resulting file is opened
       with the object cursor located at the first  object  of  the  file.  If
       ea_open()  is  invoked  with EO_TAIL specified in aflags, the resulting
       file is opened with the object cursor positioned beyond the last object
       in  the  file.  If EO_NO_VALID_HDR is set in aflags along with EO_HEAD,
       the initial header record will be returned as the first item read  from
       the  file.  When  creating  a  file, the creator argument should be set
       (system generated files use the value "SunOS"); when  reading  a  file,
       this  argument should be set to NULL if no validation is required; oth‐
       erwise it should be set to the expected value in the file.


       The ea_close() function closes an open exacct file.

RETURN VALUES
       Upon successful completion, ea_open() and ea_close() return  0.  Other‐
       wise  they  return −1 and call ea_error(3EXACCT) to return the extended
       accounting error value describing the error.

ERRORS
       The ea_open() and ea_close() functions may fail if:

       EXR_SYSCALL_FAIL    A system call invoked by the function  failed.  The
                           errno  variable contains the error value set by the
                           underlying call.



       The ea_open() function may fail if:

       EXR_CORRUPT_FILE    The file referred to by name is not a valid  exacct
                           file.


       EXR_NO_CREATOR      In  the case of file creation, the creator argument
                           was NULL. In the case of opening an existing  file,
                           a  creator argument was not NULL and does not match
                           the creator item of the exacct file.


       EXR_UNKN_VERSION    The file referred to by name uses  an  exacct  file
                           version that cannot be processed by this library.


USAGE
       The exacct file format can be used to represent data other than that in
       the extended accounting format. By using a unique creator type  in  the
       file header, application writers can develop their own format suited to
       the needs of their application.

EXAMPLES
       Example 1 Open and close exacct file.



       The following example opens the extended accounting data file for  pro‐
       cesses. The exacct file is then closed.


         #include <exacct.h>

         ea_file_t ef;
         if (ea_open(&ef, "/var/adm/exacct/proc", NULL, EO_HEAD,
             O_RDONLY, 0) == -1)
                 exit(1);
         (void) ea_close(&ef);
