Format
#include <stdio.h> int sprintf(char *buffer, const char *format-string, argument-list);
Language Level: ANSI
Threadsafe: Yes.
Description
The sprintf() function formats and stores a series of characters and values in the array buffer. Any argument-list is converted and put out according to the corresponding format specification in the format-string.
The format-string consists of ordinary characters and has the same form and function as the format-string argument for the printf() function.
Return Value
The sprintf() function returns the number of bytes that are written in the array, not counting the ending null character.
Example that uses sprintf()
This example uses sprintf() to format and print various data.
#include <stdio.h> char buffer[200]; int i, j; double fp; char *s = "baltimore"; char c; int main(void) { c = 'l'; i = 35; fp = 1.7320508; /* Format and print various data */ j = sprintf(buffer, "%s\n", s); j += sprintf(buffer+j, "%c\n", c); j += sprintf(buffer+j, "%d\n", i); j += sprintf(buffer+j, "%f\n", fp); printf("string:\n%s\ncharacter count = %d\n", buffer, j); } /********************* Output should be similar to: ************* string: baltimore l 35 1.732051 character count = 24 */
