- get user's binary preselection mask
cc [ flag... ] file... -lbsm -lsocket -lnsl [ library... ] #include <bsm/libbsm.h> int au_user_mask(char *username, au_mask_t *mask_p);
The au_user_mask() function reads the default, system wide audit classes from audit_control(4), combines them with the per-user audit classes from the audit_user(4) database, and updates the binary preselection mask pointed to by mask_p with the combined value.
The audit flags in the flags field of the audit_control(4) database and the always-audit-flags and never-audit-flags from the audit_user(4) database represent binary audit classes. These fields are combined by au_preselect(3BSM) as follows:
mask = ( flags + always-audit-flags) - never-audit-flags
file containing default parameters read by the audit daemon, auditd(1M)
file that stores per-user audit event mask
See attributes(5) for descriptions of the following attributes:
The au_user_mask() function should be called by programs like login(1) which set a process's preselection mask with setaudit(2). getaudit(2) should be used to obtain audit characteristics for the current process.
The functionality described on this manual page is available only if the Basic Security Module (BSM) has been enabled. See bsmconv(1M) for more information.
