typedef int (*str_netfd_read_t)(struct vsf_session*
* Read a string from a network socket into a string buffer object. The string
* is delimited by a specified string terminator character.
* If any network related errors occur trying to read the string, this call
* will exit the program.
* This method avoids reading one character at a time from the network.
* p_sess - the session object, used for passing into the I/O callbacks
* p_str - the destination string object
* term - the character which will terminate the string. This character
* is included in the returned string.
* p_readbuf - pointer to a scratch buffer into which to read from the
* network. This buffer must be at least "maxlen" characters!
* maxlen - maximum length of string to return. If this limit is passed,
* an empty string will be returned.
* p_peekfunc - a function called to peek data from the network
* p_readfunc - a function called to read data from the network
* -1 upon reaching max buffer length without seeing terminator, or the number
* of bytes read, _including_ the terminator. 0 for an EOF on the socket.
* Does not return (exits) for a serious socket error.
