str(3G)

NAME
     str: strfind, strrspn, strtrns - string manipulations

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

     #include <libgen.h>

     int strfind (const char *as1, const char *as2);

     char *strrspn (const char *string, const char *tc);

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

DESCRIPTION
     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
     /* 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);

     string(3C)

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