seteuid - set effective user ID SYNOPSIS
#include <unistd.h> int seteuid(uid_t uid); DESCRIPTION
If uid is equal to the real user ID or the saved set-user-ID, or if the process has appropriate privileges, seteuid() shall set the effec- tive user ID of the calling process to uid; the real user ID and saved set-user-ID shall remain unchanged. The seteuid() function shall not affect the supplementary group list in any way. RETURN VALUE
Upon successful completion, 0 shall be returned; otherwise, -1 shall be returned and errno set to indicate the error. ERRORS
The seteuid() function shall fail if: EINVAL The value of the uid argument is invalid and is not supported by the implementation. EPERM The process does not have appropriate privileges and uid does not match the real group ID or the saved set-group-ID. The following sections are informative. EXAMPLES
None. APPLICATION USAGE
None. RATIONALE
Refer to the RATIONALE section in setuid(). FUTURE DIRECTIONS
None. SEE ALSO
