PARAMETERS
|
cflags ||
Contains the bitwise inclusive OR of flags for regcomp().|
The cflags parameter is the bitwise inclusive OR of zero or more of the following |
flags. These flags are defined in the /usr/include/regex.h file. |
REG_EXTENDED ||
Uses extended regular expressions. |
REG_ICASE ||
Ignores case in match. |
REG_NOSUB ||
If this flag is not set, the regcomp() function sets the |
preg.re_nsub field to the number of parenthetic expressions |
found in the pattern parameter. Otherwise, a subexpression will |
result in an error. |
REG_NEWLINE ||
Treats newline as a special character marking the end and begin- |
ning of lines. |
