STRCASECMP(3)             OpenBSD Programmer's Manual            STRCASECMP(3)

NAME
     strcasecmp, strncasecmp - compare strings, ignoring case



SYNOPSIS
     #include <string.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 null-terminated
     strings s1 and s2 and 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 `\0'.

     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.
