 ==== description of cgets ====
-cgets is in work by code-reference.com \\
+Reads a string from the console.\\
-if you are faster... don't hasitate and add it
+\\
+cgets reads a string of characters from the console and stores the string (and the string length) in the location pointed to by str.\\
+\\
+cgets reads as long as a sign to mark the combination carriage return / line feed (CR / LF) occurs or the maximum number of characters has been read. When reading cgets the CR / LF combination is replaced by the combination of characters \ 0 (null terminator) before the string is stored.\\
+\\
+Assign str[0] before calling cgets to the maximum length of the string to be read.\\ After completion of the read operation st is assigned[1] the actual number of characters read.\\ The reading begins with the character at position str[2] and ends with the null terminator.\\ Consequently, at least str str[0] in length plus 2 bytes.\\
+return value: a pointer to str[2]\\
 <code c>
