loc1, loc2 - pointers to characters matched by regular expressions (LEGACY)
#include <regexp.h> extern char *loc1; extern char *loc2;
Refer to regexp().
These variables are kept for historical reasons, but may be withdrawn in a future issue.
New applications should use fnmatch(), glob(), regcomp() and regexec(), which provide full internationalised regular expression functionality compatible with the ISO POSIX-2 standard, as described in the XBD specification, Regular Expressions .
