These tokens are delimited - in the string by at least one of the characters in <<*<[delimiters]>>>. - The first time that <<strtok>> is called, <<*<[source]>>> should be - specified; subsequent calls, wishing to obtain further tokens from - the same string, should pass a null pointer instead. The separator - string, <<*<[delimiters]>>>, must be supplied each time and may - change between calls. - - The <<strtok>> function returns a pointer to the beginning of each - subsequent token in the string, after replacing the separator - character itself with a null character. When no more tokens remain, - a null pointer is returned. - - The <<strtok_r>> function has the same behavior as <<strtok>>, except - a pointer to placeholder <<*<[lasts]>>> must be supplied by the caller. - - The <<strsep>> function is similar in behavior to <<strtok>>, except - a pointer to the string pointer must be supplied <<<[source_ptr]>>> and - the function does not skip leading delimiters. When the string starts - with a delimiter, the delimiter is changed to the null character and - the empty string is returned. Like <<strtok_r>> and <<strtok>>, the - <<*<[source_ptr]>>> is updated to the next character following the - last delimiter found or NULL if the end of string is reached with - no more delimiters. - -RETURNS - <<strtok>>, <<strtok_r>>, and <<strsep>> all return a pointer to the - next token, or <<NULL>> if no more tokens can be found. For - <<strsep>>, a token may be the empty string. - -NOTES - <<strtok>> is unsafe for multi-threaded applications. <<strtok_r>> - and <<strsep>> are thread-safe and should be used instead. - -PORTABILITY -<<strtok>> is ANSI C. -<<strtok_r>> is POSIX. -<<strsep>> is a BSD extension. - -<<strtok>>, <<strtok_r>>, and <<strsep>> require no supporting OS subroutines. - -QUICKREF - strtok ansi impure -*/ - -/* undef STRICT_ANSI so that strtok_r prototype will be defined */ -#undef __STRICT_ANSI__ -#include <string.h> -#include <_ansi.h> -#include <reent.h> - -#ifndef _REENT_ONLY - -extern char *__strtok_r (char *, const char *, char **, int); - -char * -_DEFUN (strtok, (s, delim), - register char *s _AND - register const char *delim) -{ - _REENT_CHECK_MISC(_REENT); - return __strtok_r (s, delim, &(_REENT_STRTOK_LAST(_REENT)), 1); -} -#endif |
