setpflags
getpflags(2) getpflags(2) NAME
getpflags, setpflags - get or set process flags SYNOPSIS
#include <sys/types.h> #include <priv.h> uint_t getpflags(uint_t flag); int setpflags(uint_t flag, uint_t value); The getpflags() and setpflags() functions obtain and modify the current per-process flags. The following values for flag are supported: PRIV_AWARE This one bit flag takes the value of 0 (unset) or 1 (set). Only if this flag is set is the current process privilege- aware. A process can attempt to unset this flag but might fail silently if the observed set invariance condition cannot be met. Setting this flag is always successful. See privileges(5) for a discussion of this flag. PRIV_DEBUG This one bit flag takes the value of 0 (unset) or 1 (set). Only if this flag is set does the current process have privi- lege debugging enabled. Processes can set and unset this flag at will. The getpflags() returns the value associated with a given per-process flag. If the flag argument is invalid, (uint_t)-1 is returned and errno is set to indicate the error. Upon successful completion, setpflags() returns 0. Otherwise, -1 is returned and errno is set to indicate the error. The getpflags() and setpflags() functions will fail if: EINVAL The value of flag or the value to which the flag is set is out of range. The setpflags() function will fail if: EPERM An attempt was made to unset PRIV_AWARE but the observed set invariance condition was not met.
