strvars
STRVARS(3pub) C Programmer's Manual STRVARS(3pub)NAME
strvars - expand variables in string
SYNOPSIS
#include <publib.h>
int strvars(char **res, const char *str, char *(*expand)(const char *));
DESCRIPTION
strvars will replaces references to variables in the string str with the values of the variables. A reference to a variable is of the form
$(foo) or $x (where x is a single character, but not $). A dollar sign is expressed in the string as $$, and will be converted to $ in the
output. Memory for the expanded string is allocated dynamically, and *res is set to point to it.
The values of the variables are fetched using the function expand. It is given the name of the variable as its argument, and must return a
pointer to the value, or NULL if that variable doesn't exist.
RETURN VALUE
strvars will return 0 if successful, or NULL if an error occured (malformed input string, result too big, or unknown variable).
EXAMPLE
To replace references to environment variables, one would the following.
#include <publib.h>
#include <stdlib.h>
char line[1024];
char *res;
if (strvars(&res, line, getenv) == NULL)
errormsg(1, 0, "strvars failed");
printf("res = <%s>
", res);
