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 n);

DESCRIPTION
     The strcmp() and strncmp() functions lexicographically compare the null-terminated strings s1 and s2.

     The strncmp() function compares not more than n characters.  Because strncmp() is designed for compar-ing comparing
     ing 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, accord-ing according
     ing as 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'.

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'').
