Pgetenv —
get process environment variable
Process Control Library (libproc, -lproc)
#include
<libproc.h>
char *
Pgetenv(
struct
ps_prochandle *P,
const char *name,
char *buf,
size_t
buflen);
The
Pgetenv function searches the environment
of the process handle
P for the environment
variable named
name. If found it copies up to
buflen characters of the value, including the
null terminator, into the buffer
buf.
Everything after the
= sign is copied.
Upon successful completion, the
Pgetenv()
function returns the pointer
buf. Otherwise,
if the environment variable was not found,
NULL is returned.
