STRCASECMP(3)           NetBSD 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 `\0'. 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. NetBSD 5.0 June 9, 1993 NetBSD 5.0
