Description:
A type identifier associates a process or channel with a set of
rules in order to protect or restrict it. The security policy contains the rules for all type
identifiers. To learn more about security policies, see Security Policies
in the System Security Guide.
The posix_spawnattr_gettypeid() function retrieves the type identifier from the spawn attributes object pointed to by attrp. You must have already initialized the spawn attributes object by calling posix_spawnattr_init().
For more information about spawn attributes, see the entry for posix_spawn().
Returns:
- EOK
- Success.
- EINVAL
- The attrp pointer does not refer to a valid attribute structure.
