Psetflags() and
Punsetflags() functions manipulate the process flags
for the process handle P. The process flags determine
how the process behaves in the face of various actions. For example, setting
the PR_FORK flag indicates that the tracing flags of the
process and the inherit-on-fork mode should be set on children. A full list of
the process flags is available in the PCSET section in
proc(5).
The Psetflags() function sets the flags
specified in flags by doing a bitwise-inclusive-OR
with the previously set flags.
The Punsetflags() function removes the
flags specified in flags from the tracing flags of the
process. Items not listed in flags will remain.
To see the current set of flags active on the process, check the pr_flags member of the pstatus_t for the process. It can be obtained through the Pstatus(3PROC) function.
Note, attempting to modify the process flags only works on active processes. Attempting to call these functions of process handles corresponding to core files, zombie processes, or files, will result in an error.
Psetflags() and
Punsetflags() functions return 0.
Otherwise, -1 is returned and errno is set
to indicate the error.
