+# Generic array
+
+#### Overview
+
+- Buffer implementation for serializing data/protocol implementation.
+- Provides put/get for binary data, 8/16/32/64 bit integers, double and strings.  
+- Strings are kept length prefixed and null ended. So, no need to copy string  
+  when you are reading, you just get the pointer. This is useful to avoid memory  
+  allocation overhead.
+- Integer operations are compiled into bounds check + a single MOV instruction  
+  on x86. Buffer keeps data in Little Endian format, so on big endian systems,  
+  integer put/get is bswap(byte swap) + MOV.
+- Just copy <b>sc_buf.h</b> and <b>sc_buf.c</b> to your project.
+
+
+##### Usage
+
+```c
+#include "sc_buf.h"
+#include <stdio.h>
+
+void basic()
+{
+    struct sc_buf buf;
+    sc_buf_init(&buf, 1024);
+
+    sc_buf_put_32(&buf, 16);
+    sc_buf_put_str(&buf, "test");
+    sc_buf_put_fmt(&buf, "value is %d", 3);
+
+    printf("%d \n", sc_buf_get_32(&buf));
+    printf("%s \n", sc_buf_get_str(&buf));
+    printf("%s \n", sc_buf_get_str(&buf));
+
+    sc_buf_term(&buf);
+}
+
+void error_check()
+{
+    uint32_t val, val2;
+    struct sc_buf buf;
+
+    sc_buf_init(&buf, 1024);
+    sc_buf_put_32(&buf, 16);
+
+    val = sc_buf_get_32(&buf);
+    val2 = sc_buf_get_32(&buf); // This will set error flag in buffer;
+
+    if (sc_buf_valid(&buf) == false) {
+        printf("buffer is corrupt");
+        exit(EXIT_FAILURE);
+    }
+
+    sc_buf_term(&buf);
+}
+
+int main()
+{
+    basic();
+    error_check();
+
+    return 0;
+}
