STRCMP(3) BSD Programmer's Manual STRCMP(3)
strcmp, strncmp - compare strings
#include <string.h> int strcmp(const char *s1, const char *s2); int strncmp(const char *s1, const char *s2, size_t len);
The strcmp() and strncmp() functions lexicographically compare the NUL- terminated strings s1 and s2.
The strcmp() and strncmp() return an integer greater than, equal to, or less than 0, according to whether the string s1 is greater than, equal to, or less than the string s2. The comparison is done using unsigned characters, so that '\200' is greater than '\0'. strncmp() compares at most len characters.
