man get_attrib (Fonctions bibliothèques) - Returns needed attributes to execute a command successfully on any system.
NAME
get_attrib - Returns needed attributes to execute a command successfully on any system.
SYNOPSIS
#include "get_attrib.h" char *get_attrib (char *command_name, char *permits, char *active_categories, char *authorized_categories, long flag);
DESCRIPTION
The get_attributes routine is designed to determine the system type currently running and return the needed runcmd(1) 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.
The get_attrib arguments are as follows:
- command_name
- Pointer to the command the attributes are to be returned about.
- permits
- Pointer to either an octal or name string of permits to be added to string returned.
- active_category
- Pointer to either an octal or name string of active categories to be added to string returned.
- authorized_categories
- Pointer to either an octal or name string of categories to be added to string returned.
- flag
- 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. GA_BOTH_OFF PRIV_SU and PRIV_TFM off. GA_SU_ON PRIV_SU on. GA_TFM_ON PRIV_TFM on. GA_BOTH_ON PRIV_SU and PRIV_TFM on. GA_CURRENT_SYS Current system type.
EXAMPLE
The following example shows how get_attrib can be used to determine the needed attributes to run a command successfully:
#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\n"); exit(1); } else { sprintf(cmd, "runcmd %s mount /dev/dsk/qtest3 /qtest3", string); printf("Command = %s\n",cmd); }
if ((string = get_attrib("mount", NULL, NULL, NULL, GA_BOTH_OFF))==(char *)NULL) { printf("get_attrib() failed\n"); exit(1); } else { sprintf(cmd, "runcmd %s mount /dev/dsk/qtest3 /qtest3", string); printf("Command = %s\n",cmd); } }
On an MLS system with PRIV_SU ON the first sprintf would return, runcmd -u root mount /dev/dsk/qtest3 /qtest3.
On the same system the second sprintf would return, runcmd -J secadm -j secadm mount /dev/dsk/qtest3 /qtest3 Which is as if PRIV_TFM and PRIV_SU were OFF.
RETURN VALUE
If get_attrib() completes successfully, a pointer to a string containing the options of the runcmd string is returned; otherwise NULL is returned.
ERRORS
If get_attrib() has problems, an error message will be put in GA_Err_Msg and NULL will be returned.
