/* FUNCTION <<strcasecmp>>---case-insensitive character string compare INDEX strcasecmp ANSI_SYNOPSIS #include <string.h> int strcasecmp(const char *<[a]>, const char *<[b]>); TRAD_SYNOPSIS #include <string.h> int strcasecmp(<[a]>, <[b]>) char *<[a]>; char *<[b]>; DESCRIPTION <<strcasecmp>> compares the string at <[a]> to the string at <[b]> in a case-insensitive manner. RETURNS If <<*<[a]>>> sorts lexicographically after <<*<[b]>>> (after both are converted to uppercase), <<strcasecmp>> returns a number greater than zero. If the two strings match, <<strcasecmp>> returns zero. If <<*<[a]>>> sorts lexicographically before <<*<[b]>>>, <<strcasecmp>> returns a number less than zero. PORTABILITY <<strcasecmp>> is in the Berkeley Software Distribution. <<strcasecmp>> requires no supporting OS subroutines. It uses tolower() from elsewhere in this library. QUICKREF strcasecmp */ #include <string.h> #include <ctype.h> int _DEFUN (strcasecmp, (s1, s2), _CONST char *s1 _AND _CONST char *s2) { while (*s1 != '\0' && tolower(*s1) == tolower(*s2)) { s1++; s2++; } return tolower(*(unsigned char *) s1) - tolower(*(unsigned char *) s2); }
