strncasecmp(3) [netbsd man page]

STRCASECMP(3)						   BSD Library Functions Manual 					     STRCASECMP(3)

NAME

     strcasecmp, strncasecmp -- compare strings, ignoring case

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <strings.h>

     int
     strcasecmp(const char *s1, const char *s2);

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

DESCRIPTION

     The strcasecmp() and strncasecmp() functions compare the nul-terminated strings s1 and s2 and return an integer greater than, equal to, or
     less than 0, according to whether s1 is lexicographically greater than, equal to, or less than s2 after translation of each corresponding
     character to lower-case.  The strings themselves are not modified.  The comparison is done using unsigned characters, so that '200' is
     greater than ''.

     The strncasecmp() compares at most len characters.

SEE ALSO

     bcmp(3), memcmp(3), strcmp(3), strcoll(3), strxfrm(3)

HISTORY

     The strcasecmp() and strncasecmp() functions first appeared in 4.4BSD.

NOTES

     If len is zero strncasecmp() returns always 0.

NAME

     strcasecmp, strcasecmp_l, strncasecmp, strncasecmp_l -- compare strings, ignoring case

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <strings.h>

     int
     strcasecmp(const char *s1, const char *s2);

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

     #include <strings.h>
     #include <xlocale.h>

     int
     strcasecmp_l(const char *s1, const char *s2, locale_t loc);

     int
     strncasecmp_l(const char *s1, const char *s2, size_t n, locale_t loc);

DESCRIPTION

     The strcasecmp() and strncasecmp() functions compare the null-terminated strings s1 and s2.

     The strncasecmp() compares at most n characters.

     Although the strcasecmp() and strncasecmp() functions use the current locale, the strcasecmp_l() and strncasecmp_l() functions may be passed
     locales directly. See xlocale(3) for more information.

RETURN VALUES

     The strcasecmp() and strncasecmp() return an integer greater than, equal to, or less than 0, according as s1 is lexicographically greater
     than, equal to, or less than s2 after translation of each corresponding character to lower-case.  The strings themselves are not modified.
     The comparison is done using unsigned characters, so that '200' is greater than ''.

HISTORY

     The strcasecmp() and strncasecmp() functions first appeared in 4.4BSD.  Their prototypes existed previously in <string.h> before they were
     moved to <strings.h> for IEEE Std 1003.1-2001 (``POSIX.1'') compliance.
