NAME
strcmp, strcasecmp, strncasecmp, strncmp - compare two null-terminated strings. SYNOPSIS
#include <sys/ddi.h> int strcmp(const char *s1, const char *s2); int strcasecmp(const char *s1, const char *s2); int strncasecmp(const char *s1, const char *s2, size_t n); int strncmp(const char *s1, const char *s2, size_t n); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). PARAMETERS
s1, s2 Pointers to character strings. n Count of characters to be compared. DESCRIPTION
strcmp() strcmp() returns 0 if the strings are the same, or the integer value of the expression (*s1 - *s2) for the last characters compared if they differ. strcasecmp(), strncasecmp() The strcasecmp() and strncasecmp() functions are case-insensitive versions of strcmp() and strncmp(), respectively, described in this sec- tion. They assume the ASCII character set and ignore differences in case when comparing lowercase and uppercase characters. strncmp() strncmp() returns 0 if the first n characters of s1 and s2 are the same, or (*s1 - *s2) for the last characters compared if they dif- fer. RETURN VALUES
strcmp() returns 0 if the strings are the same, or (*s1 - *s2) for the last characters compared if they differ. strcasecmp() and strncasecmp() return values in the same fashion as strcmp() and strncmp(), respectively. strncmp() returns 0 if the first n characters of strings are the same, or (*s1 - *s2) for the last characters compared if they differ. CONTEXT
These functions can be called from user or interrupt context. SEE ALSO

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 comparing strings rather than binary data, characters that appear after a '' 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 unsigned characters, so that '200' is greater than ''. 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
