...matches, each subpattern, from left to right, matches the longest possible string. For this purpose, a null string is considered to be longer than no match at all. For example, matching the BRE \(.*\).* against abcdef, the subexpression (\1) is abcdef, and matching the BRE \(a*\)* against bc...

...to the USB?. getsUSBUSART. Read a string from the USB. mCDCGetRxLength. Read the length of the last string read from the USB. putrsUSBUSART. putrsUSBUSART writes a string of data to the USB including the null character. Use this version to transfer literal strings. of data, or data located in program...

If there are two successive occurrences, the field between them simply has the empty string as its value.Finally, if you specify more than a single character as the field separator, it will be interpreted as a regular expression. That is, the field separator will be the "leftmost longest non-null...
