+ * NAME
+ *    memset_s
+ *
+ * SYNOPSIS
+ *    #include "safe_mem_lib.h"
+ *    errno_t
+ *    memset_s(void *dest, rsize_t len, uint8_t value)
+ *
+ * DESCRIPTION
+ *    Sets len bytes starting at dest to the specified value.
+ *
+ * SPECIFIED IN
+ *    ISO/IEC JTC1 SC22 WG14 N1172, Programming languages, environments
+ *    and system software interfaces, Extensions to the C Library,
+ *    Part I: Bounds-checking interfaces
+ *
+ * INPUT PARAMETERS
+ *    dest       pointer to memory that will be set to the value
+ *
+ *    len        number of bytes to be set
+ *
+ *    value      byte value
+ *
+ * OUTPUT PARAMETERS
+ *    dest      is updated
+ *
+ * RUNTIME CONSTRAINTS
+ *    dest shall not be a null pointer.
+ *    len shall not be 0 nor greater than RSIZE_MAX_MEM.
+ *    If there is a runtime constraint, the operation is not performed.
+ *
+ * RETURN VALUE
+ *    EOK        successful operation
+ *    ESNULLP    NULL pointer
+ *    ESZEROL    zero length
+ *    ESLEMAX    length exceeds max limit
+ *
+ * ALSO SEE
+ *    memset16_s(), memset32_s()
