 10.3 Regular Expression Matching
 ================================
 
 The GNU C Library supports two interfaces for matching regular
 expressions.  One is the standard POSIX.2 interface, and the other is
 what the GNU C Library has had for many years.
 
    Both interfaces are declared in the header file 'regex.h'.  If you
 define '_POSIX_C_SOURCE', then only the POSIX.2 functions, structures,
 and constants are declared.

 
* POSIX Regexp Compilation    Using 'regcomp' to prepare to match.
* Flags for POSIX Regexps     Syntax variations for 'regcomp'.
* Matching POSIX Regexps      Using 'regexec' to match the compiled
 				   pattern that you get from 'regcomp'.
* Regexp Subexpressions       Finding which parts of the string were matched.
* Subexpression Complications Find points of which parts were matched.
* Regexp Cleanup              Freeing storage; reporting errors.
