NAME

       strgsub - substitute all occurrences of pattern with another string

SYNOPSIS

       #include <publib.h>
       int strgsub(char *str, const char *pat, const char *sub, size_t max);

DESCRIPTION

       strgsub finds all occurrences of the pattern pat in the string str (using a method similar
       to  strstr(3)  to  find  the occurrences, i.e., no regular expressions), and replaces each
       with sub. If pat does not occur in str, no substitution is made.  The size (including  the
       terminating  '\0')  of the string after the substitutions may be at most max chars.  If it
       would be larger, no substitutions are made.

       Of course, if sub is an empty string, the occurrences of the pattern are deleted from  the
       string.

RETURN VALUE

       strgsub  returns  the number of substitutions made, or -1 if the result would not have fit
       into max chars.

EXAMPLE

       To substitute every "foo" with "bar" in a line, one might do the following.

            strgsub(line, "foo", "bar", strlen(line)+1);
