PMSETPROCESSIDENTITY(3) Library Functions Manual PMSETPROCESSIDENTITY(3)
pmSetProcessIdentity - set process user and group id
#include <pcp/pmapi.h>
int pmSetProcessIdentity(const char *username);
cc ... -lpcp
pmSetProcessIdentity provides a platform-independent method to
set the user id of a process to that matching username.
If possible (when the caller is already running as root)
pmSetProcessIdentity will set the group id of the process to that
of the matching user, e.g. using username and getpwnam(3).
A return value of 0 indicates success, otherwise the return value
is an error code that may be decoded with pmErrStr(3).
pmSetProcessIdentity is most often used in conjunction with
pmGetUsername(3) at process start up.
getpwnam(3), PMAPI(3), pmErrStr(3), pmGetUsername(3), setgid(3)
and setuid(3).
