Function Documentation

void rtxFreeRegexpCache ( OSCTXT pctxt  ) 

This function frees the memory associated with the regular expression cache. The regular expression cache is designed to use memory that survives calls to rtxMemFree and rtxMemReset, therefore it is necessary to call this function to free that memory. (Note that rtxFreeContext invokes this.)

OSBOOL rtxMatchPattern ( OSCTXT pctxt,
const OSUTF8CHAR *  text,
const OSUTF8CHAR *  pattern 
)

This function compares the given string to the given pattern. It returns true if match, false otherwise.

Parameters:
