SYNOPSIS
#include
char *strsep(char **stringp, const char *delim);
DESCRIPTION
The
str function strsep is used to walk through a
delim-delimited list of
tokens located in
stringp. Note that
stringp is a pointer to a string pointer -
strsep uses
stringp to hold its state information - it increments it as it goes along.
Returns a pointer to a string containing the token it just parsed.
NOTES
The man pages has this to say:
The strsep() function was introduced as a replacement for
strtok(), since the latter cannot handle empty fields.
(However, strtok() conforms to ANSI-C and hence is more
portable.)
As for me, I think that the best way to deal with this problem would be to write a little
#ifdef'ed macro, which points to
strsep when possible, or else a hand-written replacement...
The uses for this function are plural. Write your next language parser with it! Read comma-delimited data!
