It's not an error for it to not send it all. If it returns 0 or -1, it's an error.

Code:
void send_message(int client_socket_fd, char *message, int length) {
    int pos=0;

    while(pos < length)
    {
        size_t bytes = write(client_socket_fd, message+pos, length-pos);
        if(bytes <= 0)
        {
            perror("Socket error");
            return;
        }

        pos += bytes;
    }
}

It's not an error to not receive it all, either. You have to keep reading until you know you're done. You don't know how long the message will actually be unless your server tells you somehow, which is why I suggested using \n or \n to mark the end of a record and showed receiving code that looked for that.

get_midi_length(3alleg4)					  Allegro manual					  get_midi_length(3alleg4)

NAME
get_midi_length - Determines the total playing time of a midi, in seconds. Allegro game programming library. SYNOPSIS
#include <allegro.h> int get_midi_length(MIDI *midi); DESCRIPTION
This function will simulate playing the given MIDI, from start to end, to determine how long it takes to play. After calling this function, midi_pos will contain the negative number of beats, and midi_time the length of the midi, in seconds. Note that any currently playing midi is stopped when you call this function. Usually you would call it before play_midi, to get the length of the midi to be played, like in this example: length = get_midi_length(my_midi); play_midi(my_midi); do { pos = midi_time; textprintf_ex(screen, font, 0, 0, c, -1, "%d:%02d / %d:%02d ", pos / 60, pos % 60, length / 60, length % 60); rest(100); } while(pos <= length); RETURN VALUE
Returns the value of midi_time, the length of the midi. SEE ALSO
load_midi(3alleg4), midi_time(3alleg4), midi_pos(3alleg4), exmidi(3alleg4) Allegro version 4.4.2 get_midi_length(3alleg4)
