regcmp

/usr/ccs/bin/regcmp [-] files

Stands for "regular expression compile." Compile the regular expressions in one or more files and place output in file.i (or in file.c if - is specified). The output is C source code, while the input entries in files are of the form:

C variable     "regular expression"

The purpose of this program is to precompile regular expressions for use with the regex(3C) library routine, avoiding the overhead of the regcmp(3C) function.
