|
|
.SH SYNOPSIS
|
|
.B #include <proc/readproc.h>
|
|
.sp
|
|
.BI "proc_t* readproc(PROCTAB *" PT ", proc_t *" return_buf ");"

|
.SH DESCRIPTION
|
|
|
|
.B readproc
|
|
reads the information for the next process matching the criteria
|
|
specified in
|
|
.I PT
|
|
and fills them into a
|
|
.I proc_t
|
|
structure. If
|
|
.I return_buf
|
|
is not NULL, it will use the struct pointed at by
|
|
.IR return_buf .
|
|
Otherwise it will allocate a new
|
|
.I proc_t
|
|
structure and return a pointer to it.
|
|
Note that (if so specified in
|
|
.IR PT )
|
|
readproc always allocates memory if it fills in the
|
|
.IR environ " or " cmdline
|
|
parts of
|
|
.IR proc_t .
|
|
|
|
.B freeproc
|
|
frees all memory allocated for the
|
|
.I proc_t
|
|
struct
|
|
.IR *p .
|
|
|
|
The
|
|
.I proc_t
|
|
structure is defined in
|
|
.IR <proc/readproc.h> ,
|
|
please look there for a definition of all fields.
|
|
|
|
.SH "RETURN VALUE"
|
|
|
|
.B readproc
|
|
returns a pointer to the next
|
|
.I proc_t
|
|
or NULL if there are no more processes left.
