hola,

estoy probando el siguiente c�digo y errno me dice al llamar a write que 
el fd no es correcto. �qu� estoy haciendo mal?

gracias

un saludo


int write_log(char *texto,char *strfile)
{
	struct tm *strtime;
	int fd;
	time_t clock;	
	char date[LEN_DATE];
	char buffer[LEN_LOG_LINE+LEN_DATE+1];
		
	/* abrimos el fichero para escritura y lo creamos si no existe */
	if((fd  = open(strfile,O_APPEND | O_CREAT, 0644))<0){
		printf("Error al crear el fichero de log\n");
		fflush(stdout);
		return ERROR;
	}

	time(&clock);
   	strtime=localtime(&clock);
	strftime(date,LEN_DATE,"%Y%m%d:%H%M%S ",strtime);
	strcat(buffer,date);
	strcat(buffer,texto);
	if(write(fd,buffer,strlen(buffer))<0){
		printf("Error al escribir el fichero de log\n");
		fflush(stdout);
		close(fd);
		return ERROR;
	}
	close(fd);
}
