strcmp - compare two strings

Syntax	#include <string.h> int strcmp(const char *s1, const char *s2);
Description	strcmp() compares strings s1 and s2 lexically, e.g.: "circle" is lexically less than "circular"; "bustle" is lexically greater than "bus".
Return val.	Integer value:
	< 0 = 0 > 0	s1 is lexically less than s2. s1 and s2 are lexically equal. s1 is lexically greater than s2.
Notes	Strings terminated with the null byte (\0) are expected as arguments. If this is not the case, the result is random. The collating sequence is based on the EBCDIC character set.
