KINFO_GETPROC(3)       FreeBSD Library Functions Manual       KINFO_GETPROC(3)

NAME

     kinfo_getproc - function for getting process information from kernel

LIBRARY

     System Utilities Library (libutil, -lutil)

SYNOPSIS

     #include <sys/types.h>
     #include <sys/user.h>
     #include <libutil.h>

     struct kinfo_proc *
     kinfo_getproc(pid_t pid);

DESCRIPTION

     This function is used for obtaining process information from the kernel.

     The pid field contains the process identifier.  This should be a process
     that you have privilege to access.  This function is a wrapper around
     sysctl(3) with the KERN_PROC_PID mib.  While the kernel returns a packed
     structure, this function expands the data into a fixed record format.

RETURN VALUES

     On success the kinfo_getproc() function returns a pointer to a struct
     kinfo_proc structure as defined by <sys/user.h>.  The pointer was
     obtained by an internal call to malloc(3) and must be freed by the caller
     with a call to free(3).  On failure the kinfo_getproc() function returns
     NULL.

SEE ALSO

     free(3), malloc(3), sysctl(3)

     The kinfo_getproc() function first appeared in FreeBSD 7.0.
