【经验共享】VxWorks 对挂接到系统中钩子函数的限制

User-installed switch hooks are called within the kernel context. Therefore, switch hooks do not have access to all VxWorks facilities. The following routines can be called from within a task switch hook:

Library                 Routines

bLib                   All routines
fppArchLib             fppSave( ), fppRestore( )
intLib                 intContext( ), intCount( ), intVecSet( ), intVecGet( )
lstLib                 All routines
mathALib               All routines, if fppSave( )/fppRestore( ) are used
rngLib                 All routines except rngCreate( )
taskLib                taskIdVerify( ), taskIdDefault( ), taskIsReady( ), taskIsSuspended( ),taskTcb( )
vxLib                  vxTas( )
