.TH GET_ATTRIB 3 07/25/2000 "Linux Test Project"
.SH NAME
\fBget_attrib\fR \- Returns needed attributes to execute a command successfully on any system.
.SH SYNOPSIS
.sp
\fB#include "get_attrib.h"\fR
.sp
\fBchar *get_attrib (char *\fIcommand_name\fB, char *\fIpermits\fB, char *\fIactive_categories\fB, char *\fIauthorized_categories\fB, long \fIflag\fR);\fR
.SH DESCRIPTION
The \fBget_attributes\fR routine is designed to determine the system type
currently running and return the needed \fBruncmd(1)\fR string to run the
command specified successfully on any 7.0 and above systems.  On systems
with TFM configured 'ON' some commands need special attributes that can't
be determined easily, this routine then uses an internal table to return the
needed attributes to run the command.  On other system types the needed
attributes are easily determined without use of this table.
.PP
The \fBget_attrib\fR arguments are as follows:
.TP 10
\fIcommand_name\fR
Pointer to the command the attributes are to be returned about.
.TP
\fIpermits\fR
Pointer to either an octal or name string of permits to be
added to string returned.
.TP
\fIactive_category\fR
Pointer to either an octal or name string of active categories to be
added to string returned.
.TP
\fIauthorized_categories\fR
Pointer to either an octal or name string of categories to be
added to string returned.
.TP
\fIflag\fR
Long set to any combination of values defined in get_attrib.h.  These values
are used to specify that the string returned should be for the specified
system type.
.sp
	\fBGA_BOTH_OFF   \fR	PRIV_SU and PRIV_TFM off.
.sp
	\fBGA_SU_ON      \fR	PRIV_SU on.
.sp
	\fBGA_TFM_ON     \fR	PRIV_TFM on.
.sp
	\fBGA_BOTH_ON    \fR	PRIV_SU and PRIV_TFM on.
.sp
	\fBGA_CURRENT_SYS\fR	Current system type.
.sp
.PP
.SH "EXAMPLE"
.P
The following example shows how \fBget_attrib\fR can be used to determine
the needed attributes to run a command successfully:
.P
.nf
#include <stdio.h>
#include "get_attrib.h"

main()
{
 char cmd[256];
 char *string;

 if ((string =
      get_attrib("mount",NULL,NULL,NULL,GA_CURRENT_SYS)) == (char *)NULL) {
    printf("get_attrib() failed\en");
    exit(1);
 } else {
    sprintf(cmd, "runcmd %s mount /dev/dsk/qtest3 /qtest3", string);
    printf("Command = %s\en",cmd);
 }


 if ((string =
      get_attrib("mount", NULL, NULL, NULL, GA_BOTH_OFF))==(char *)NULL) {
    printf("get_attrib() failed\en");
    exit(1);
 } else {
    sprintf(cmd, "runcmd %s mount /dev/dsk/qtest3 /qtest3", string);
    printf("Command = %s\en",cmd);
 }
}
.ni

On an MLS system with PRIV_SU ON the first sprintf would return,
\fBruncmd -u root mount /dev/dsk/qtest3 /qtest3\fR.

On the same system the second sprintf would return, \fBruncmd -J secadm -j
secadm  mount /dev/dsk/qtest3 /qtest3\fR  Which is as if PRIV_TFM and PRIV_SU
were OFF.
.PP
.SH "RETURN VALUE"
If \fBget_attrib()\fR completes successfully, a pointer to a string
containing the options of the runcmd string is returned; otherwise NULL is
returned.
.SH ERRORS
If \fBget_attrib()\fR has problems, an error message will be put in GA_Err_Msg
and NULL will be returned.
.SH "SEE ALSO"
