_bprintf()

generate output into a fixed-length string

Synopsis:

#include <stdio.h>
int _bprintf( char *buf, 
              size_t bufsize,
              const char *format, ... );

Description:

The _bprintf() function is equivalent to the sprintf() function, except that the argument bufsize specifies the size of the character array buf into which the generated output is placed. A null character is placed at the end of the generated character string. The format string is described under the description of the printf() function.

Returns:

The number of characters written into the array, not counting the terminating null character. An error can occur while converting a value for output. When an error has occurred, errno contains a value indicating the type of error that has been detected.

Examples:

#include <stdio.h>

void main( int argc, char *argv[] )
  {
    char file_name[9];
    char file_ext[4];

    _bprintf( file_name, 9, "%s", argv[1] );
    _bprintf( file_ext,  4, "%s", argv[2] );
    printf( "%s.%s\n", file_name, file_ext );
  }
