.Lb libutil

SYNOPSIS


.In sys/types.h
.In sys/user.h
.In 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
.Vt struct kinfo_proc structure as defined by
.In 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)
