ph_set_sendhook(3) C Library Calls ph_set_sendhook(3)NAME
ph_set_sendhook, ph_set_recvhook - set libphclient debugging hooks
SYNOPSIS
#include <phclient.h>
typedef void (*ph_debug_func_t)(void *, char *);
void ph_set_sendhook(PH *ph, ph_debug_func_t sendfunc);
void ph_set_recvhook(PH *ph, ph_debug_func_t recvfunc);
void ph_set_hookdata(PH *ph, void *hook_data);
VERSION
This man page documents version 1.2 of libphclient.
DESCRIPTION
The ph_set_sendhook() and ph_set_recvhook() functions set the libph‐
client sending and receiving hooks to point to the application- sup‐
plied functions sendfunc and recvfunc, respectively.
Once these hooks are set, when each line of data is sent to or received
from the PH server, the sendfunc and recvfunc functions are called with
two arguments. The first is a pointer to application-specific data
(set by the ph_set_hookdata() function). The second is a pointer to
the line that was sent to or received from the server. This is typi‐
cally used by the application to monitor and debug the communication
between the library and the PH server.
To unset the send and receive hooks, applications can call ph_set_send‐
hook() and ph_set_recvhook() with a second argument of NULL.
