strcasecmp(3)							 strcasecmp(3)

NAME
       strcasecmp, strncasecmp - Perform 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 );

LIBRARY
       Standard C Library (libc)

STANDARDS
       Interfaces  documented on this reference page conform to industry stan‐
       dards as follows:

       strcasecmp(), strncasecmp():  XPG4-UNIX

       Refer to the standards(5) reference page	 for  more  information	 about
       industry standards and associated tags.

PARAMETERS
       Points  to  a  location	containing first string.  Points to a location
       containing the second of two strings referenced.	 Specifies the maximum
       number of bytes to compare.

DESCRIPTION
       The  strcasecmp()  function  compares  the  string pointed to by the s1
       parameter to the string pointed to by the s2 parameter, while  ignoring
       differences  in case. The strncasecmp() function is similar to the str‐
       casecmp function, but also compares size. If the size specified by n is
       reached	before a null, the comparison stops. Note that these functions
       work for 7-bit ASCII compares only and should not be used  in  interna‐
       tionalized applications.

RETURN VALUES
       Upon  completion,  the  strcasecmp()  function returns an integer whose
       value is greater than, equal to, or less than 0	(zero),	 according  to
       whether	the  s1	 string,  ignoring case, is greater than, equal to, or
       less than the s2 string.

       Upon successful completion, the strncasecmp() function returns an inte‐
       ger  whose  value  is  greater  than,  equal to, or less than 0 (zero),
       according to whether the s1 array (possibly null-terminated),  ignoring
       case,  is  greater than, equal to, or less than the s2 string (possibly
       null-terminated).
