Adds an API-based project definition to the kernel project registry.
The libaacct.a library.
<sys/aacct.h>
addproj(struct project *)The addproj subroutine defines the application-based project definition to the kernel repository. An application can assign a project defined in this way using the proj_execve system call.
Projects that are added this way are marked as being specified by applications so that they do not overlap with system administrator-specified projects defined using the projctl command. The PROJFLAG_API flag is turned on in the structure project to indicate that the project definition was added by an application.
Projects added by a system administrator using the projctl command are flagged as being derived from the local or LDAP-based project repositories by the PROJFLAGS_LDAP or PROJFLAGS_PDF flag. If one of these flags is specified, the addproj subroutine fails with EPERM.
The getproj routine can be used to determine the origin of a loaded project.
The addproj validates the input project number to ensure that it is within the expected range of 0x00000001 - 0x00ffffff. It also validates that the project name is a POSIX compliant alphanumeric character string. If any invalid input is found errno will be set to EINVAL and the addproj subroutine returns -1.
