STRCMP(3) BSD Library Functions Manual STRCMP(3) NAME strcmp, strncmp -- compare strings LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <string.h> int strcmp(const char *s1, const char *s2); int strncmp(const char *s1, const char *s2, size_t len); DESCRIPTION The strcmp() and strncmp() functions lexicographically compare the null- terminated strings s1 and s2. The strncmp() function compares not more than len characters. Because strncmp() is designed for comparing strings rather than binary data, characters that appear after a `\0' character are not compared. RETURN VALUES The strcmp() and strncmp() functions return an integer greater than, equal to, or less than 0, according as the string s1 is greater than, equal to, or less than the string s2. The comparison is done using un- signed characters, so that `\200' is greater than `\0'. SEE ALSO bcmp(3), memcmp(3), strcasecmp(3), strcoll(3), strxfrm(3), wcscmp(3) STANDARDS The strcmp() and strncmp() functions conform to ISO/IEC 9899:1990 ("ISO C90"). BSD October 11, 2001 BSD
