PROLOG

       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

NAME

       strcasecmp, strncasecmp - case-insensitive string comparisons

SYNOPSIS

       #include <strings.h>

       int strcasecmp(const char *s1, const char *s2);
       int strncasecmp(const char *s1, const char *s2, size_t n);

DESCRIPTION

       The strcasecmp() function shall compare, while ignoring differences in case, the string pointed to by s1 to the string pointed  to  by  s2.
       The strncasecmp() function shall compare, while ignoring differences in case, not more than n bytes from the string pointed to by s1 to the
       string pointed to by s2.

       In the POSIX locale, strcasecmp() and strncasecmp() shall behave as if the strings had been converted to lowercase and then a byte compari-
       son performed. The results are unspecified in other locales.

RETURN VALUE

       Upon  completion,  strcasecmp() shall return an integer greater than, equal to, or less than 0, if the string pointed to by s1 is, ignoring
       case, greater than, equal to, or less than the string pointed to by s2, respectively.

       Upon successful completion, strncasecmp() shall return an integer greater than, equal to, or less than 0, if the  possibly  null-terminated
       array pointed to by s1 is, ignoring case, greater than, equal to, or less than the possibly null-terminated array pointed to by s2, respec-
       tively.

NAME

       strncmp - compare part of two strings

SYNOPSIS

       #include <string.h>

       int strncmp(const char *s1, const char *s2, size_t n);

DESCRIPTION

       The strncmp() function shall compare not more than n bytes (bytes that follow a null byte are not compared) from the array pointed to by s1
       to the array pointed to by s2.

       The  sign of a non-zero return value is determined by the sign of the difference between the values of the first pair of bytes (both inter-
       preted as type unsigned char) that differ in the strings being compared.

RETURN VALUE

       Upon successful completion, strncmp() shall return an integer greater than, equal to, or less than 0, if the possibly null-terminated array
       pointed to by s1 is greater than, equal to, or less than the possibly null-terminated array pointed to by s2 respectively.

ERRORS

       No errors are defined.
