No warnings concerning length errors are produced by snprintf , and the only indication that the output may have been truncated or is incomplete is a negative return value. IMPLEMENTATIONThe snprintf function, when invoked with a limit greater than 512 characters, calls the malloc function to obtai...
Not all platforms null terminate a string when snprintf is used, and the buffer is not large enough (i.e. the end string gets truncated.) The safer way to do this is: char buf[48]; snprintf(buf,sizeof(buf),"%s",some_long_string); buf[sizeof(buf)-1] =0; This will be a no...
stream - output file stream to write to buffer - pointer to a character string to write to buf_size - up to buf_size - 1 characters may be written, plus the null terminator format - pointer to a null-terminated multibyte string specifying how to interpret the data ... - ...
If size is zero, nothing is written and str may be null. Otherwise, output characters beyond the n-1st are discarded rather than being written to str, and a nul character is wr...
If the output was truncated due to this limit then the return value is the number of characters (not including the trailing '\0') which would have been written to the final string if enough space had been available. Thus, a return value of size or more means that the output was ...
int output_len = 0; output_len =snprintf( buffer, 80, "For the input values %lf, %lf," " and %lf, the result was %lf.\n", x, y, z, a ); puts( buffer ); if ( output_len >= 80 ) fprintf( stderr, "Output string truncated! Lost %d characters.\n", output_len − 79...
Upon successful return, these functions return the number of characters printed (excluding the null byte used to end output to strings). The functions snprintf() and vsnprintf() do not write more than size bytes (including the terminating null byte ('\0')). If the output was truncated due...
