NAME    [Toc]    [Back]

     str: strfind, strrspn, strtrns - string manipulations

SYNOPSIS    [Toc]    [Back]

     cc	[flag ...] file	...  -lgen [library ...]

     #include <libgen.h>

     int strfind (const	char *as1<b>, const char *as2<b>);

     char *strrspn (const char *string<b>,	const char *tc<b>);

     char * strtrns (const char	*str<b>, const char *old<b>, const char *new<b>,
	 char *result<b>);

DESCRIPTION    [Toc]    [Back]

     strfind returns the offset	of the second string, as2, if it is a
     substring of string as1.

     strrspn returns a pointer to the first character in the string to be
     trimmed (all characters from the first character to the end of string are
     in	tc).

     strtrns transforms	str and	copies it into result.	Any character that
     appears in	old is replaced	with the character in the same position	in
     new.  The new result is returned.

EXAMPLES    [Toc]    [Back]

     /*	find pointer to	substring "hello" in as1 */
     i = strfind(as1, "hello");

     /*	trim junk from end of string */
     s2	= strrspn(s1, "*?#$%");
     *s2 = '\0';
     /*	transform lower	case to	upper case */
     a1[] = "abcdefghijklmnopqrstuvwxyz";
     a2[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
     s2	= strtrns(s1, a1, a2, s2);

DIAGNOSTICS    [Toc]    [Back]

     If	the second string is not a substring of	the first string strfind
     returns -1.
