请注意，% some_pos_int_N输出在(-N ...N)范围内，因此建议使用unsignedmath来避免'-'符号。

No warnings concerning length errors are produced bysnprintf, and the only indication that the output may have been truncated or is incomplete is a negative return value. IMPLEMENTATION Thesnprintffunction, when invoked with a limit greater than 512 characters, calls themallocfunction to obtain a te...

; int ret; // 使用snprintf将格式化字符串写入buffer ret = snprintf(buffer, sizeof(buffer), "%s", input); // 检查是否发生了截断 if (ret >= sizeof(buffer)) { // 输出被截断,需要处理这种情况 printf("Output was truncated. Full length would have been %d characters. ", ret); // ...
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...
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...
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 ...
