If pat does not occur in str, no substitution is made. The size (including the terminat- ing ' ') 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 occurences of the pattern are deleted from the string.RETURN VALUEstrgsub returns the number of substitutions made, or -1 if the result would not have fit into max chars.EXAMPLETo substitute every "foo" with "bar" in a line, one might do the following. strgsub(line, "foo", "bar", strlen(line)+1);SEE ALSOpublib(3), strstr(3), strsub(3)AUTHORLars Wirzenius (lars.wirzenius@helsinki.fi) Publib C Programmer's Manual STRGSUB(3pub)
