ustrtok_r(3alleg4) Allegro manual ustrtok_r(3alleg4)NAME
ustrtok_r - Reentrant function to retrieve tokens from a string. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
char *ustrtok_r(char *s, const char *set, char **last);
DESCRIPTION
Reentrant version of ustrtok. The `last' parameter is used to keep track of where the parsing is up to and must be a pointer to a char *
variable allocated by the user that remains the same while parsing the same string. Example:
char *word, *last;
char string[]="some-words with dashes";
char *temp = ustrdup(string);
word = ustrtok_r(string, " -", &last);
while (word) {
allegro_message("Found `%s'
", word);
word = ustrtok_r(NULL, " -", &last);
}
free(temp);
RETURN VALUE
Returns a pointer to the token, or NULL if no more are found. You can free the memory pointed to by `last' once NULL is returned.

ustrtok - Retrieves tokens from a string. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
char *ustrtok(char *s, const char *set);
DESCRIPTION
This function retrieves tokens from `s' which are delimited by characters from `set'. To initiate the search, pass the string to be
searched as `s'. For the remaining tokens, pass NULL instead. Warning: Since ustrtok alters the string it is parsing, you should always
copy the string to a temporary buffer before parsing it. Also, this function is not re-entrant (ie. you cannot parse two strings at the
same time). Example:
char *word;
char string[]="some-words with dashes";
char *temp = ustrdup(string);
word = ustrtok(temp, " -");
while (word) {
allegro_message("Found `%s'
", word);
word = ustrtok(NULL, " -");
}
free(temp);
RETURN VALUE
Returns a pointer to the token, or NULL if no more are found.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it
