C 7 strsep - separate strings

#include <string.h>

char *
strsep(char **stringp, char *delim);

Strsep locates in the null-terminated string at *stringp the first occurence of any character in delim and replaces this with a '\e0', records the location of the immediate following character in *stringp , then returns the original value of *stringp . If no delimiter characters are found, strsep sets *stringp to NULL; if *stringp is initially NULL, strsep returns NULL. The following uses strsep to parse strings containing runs of white space, making up an argument vector:

char inputstring[100];
char **argv[51], **ap = argv, *p, *val;
 "/* set up inputstring */" for (p = inputstring; p != NULL; ) {
 while ((val = strsep(&p, " \et")) != NULL && *val == '\e0');
 *ap++ = val;
}
*ap = 0;
