## NAME

gnutls\_system\_recv\_timeout - API function

## SYNOPSIS

**#include \<gnutls/gnutls.h\>**

**int gnutls\_system\_recv\_timeout(gnutls\_transport\_ptr\_t** *ptr***, unsigned int** *ms***);**

## ARGUMENTS

- gnutls\_transport\_ptr\_t ptr

  A file descriptor (wrapped in a gnutls\_transport\_ptr\_t pointer)

## DESCRIPTION

Wait for data to be received from the provided socket ( *ptr* ) within a timeout period in milliseconds, using **select()** on the provided  *ptr* .
