The function dprintf() is the same as fprintf() except that it outputs to a file descriptor, fd, instead of to a stdio(3) stream. The functions snprintf () and vsnprintf () write at most size bytes (including the terminating null byte ('\0')) to str .
The functions printf() and vprintf() write output to stdout, the standard output stream; fprintf() and vfprintf() write output to the given output stream; sprintf(), snprintf(), vsprintf() and vsnprintf() write to the character string str.
Formatted output functions. val fprintf : Pervasives.out_channel ->('a, Pervasives.out_channel, unit) Pervasives.format -> 'a. fprintf outchan format arg1 ... argN formats the arguments arg1 to argN according to the format string format , and outputs the resulting string on the channel outchan .
EXAMPLES To print a date and time in the form "Sunday, July 3, 10:02", where weekday and month are pointers to strings: #include <stdio.h> fprintf(stdout, "%s, %s %d, %.2d:%.2d\n", weekday, month, day, hour, min); To print pi to five decimal places: #include <math.h> #include <stdio.h> fprintf(stdout, "pi = %.5f\n", 4 * atan(1.0)); To allocate ...
DESCRIPTION. The functions in the printf() family produce output according to a for- mat as described below. The functions printf() and vprintf() write. output to stdout, the standard output stream; fprintf() and vfprintf() write output to the given output stream; sprintf(), snprintf(),
