.SH SYNOPSIS
\f4#include <sys/frs.h>\f1
.br
\f4#include <pthread.h>\f1
.P
\f4int frs_pinsert(frs_t* \f2frs\fP, int \f2minor_frame\fP, pid_t \f2target_pid\fP, int \f2discipline\fP, pid_t \f2base_pid\fP);\f1
.P
\f4int frs_pthread_insert(frs_t* \f2frs\fP, int \f2minor_index\fP, pthread_t \f2target_pthread\fP, int \f2discipline\fP, pthread_t \f2base_pthread\fP);\f1

.SH DESCRIPTION
\f4frs_pinsert\fP inserts the \f2target_pid\fP process after the specified
\f2base_pid\fP process in the \f2minor_frame\fP queue of \f2frs\fP.
.P
\f4frs_pthread_insert\fP inserts the \f2target_pthread\fP after the specified
\f2base_pthread\fP in the \f2minor_frame\fP queue of \f2frs\fP.

Upon successful completion, \f4frs_pinsert\fP and \f4frs_pthread_insert\fP
will return 0.
Otherwise, -1 is returned and errno is set to indicate the error.
