[edk2-devel] [PATCH v13 3/6] RedfishPkg/RedfishCrtLib: Redfish C runtime library
Abner Chang
abner.chang at hpe.com
Fri Jan 8 06:37:10 UTC 2021
Redfish CRT library is currently used by edk2 JsonLib
(open source jansson project) and edk2 RedfishLib
(libredfish open source project). Redfish CrtLib library
provides the necessary C runtime equivalent edk2 functions
for open source projects.

+/** The strtol, strtoll, strtoul, and strtoull functions convert the initial
+ portion of the string pointed to by nptr to long int, long long int,
+ unsigned long int, and unsigned long long int representation, respectively.
+ First, they decompose the input string into three parts: an initial,
+ possibly empty, sequence of white-space characters (as specified by the
+ isspace function), a subject sequence resembling an integer represented in
+ some radix determined by the value of base, and a final string of one or
+ more unrecognized characters, including the terminating null character of
+ the input string. Then, they attempt to convert the subject sequence to an
+ integer, and return the result.
+
+ If the value of base is zero, the expected form of the subject sequence is
+ that of an integer constant, optionally preceded
+ by a plus or minus sign, but not including an integer suffix. If the value
+ of base is between 2 and 36 (inclusive), the expected form of the subject
+ sequence is a sequence of letters and digits representing an integer with
+ the radix specified by base, optionally preceded by a plus or minus sign,
+ but not including an integer suffix. The letters from a (or A) through z
+ (or Z) are ascribed the values 10 through 35; only letters and digits whose
+ ascribed values are less than that of base are permitted. If the value of
+ base is 16, the characters 0x or 0X may optionally precede the sequence of
+ letters and digits, following the sign if present.
+
+ The subject sequence is defined as the longest initial subsequence of the
+ input string, starting with the first non-white-space character, that is of
+ the expected form. The subject sequence contains no characters if the input
+ string is empty or consists entirely of white space, or if the first
+ non-white-space character is other than a sign or a permissible letter or digit.
+
+ If the subject sequence has the expected form and the value of base is
+ zero, the sequence of characters starting with the first digit is
+ interpreted as an integer constant. If the subject sequence has the
+ expected form and the value of base is between 2 and 36, it is used as the
+ base for conversion, ascribing to each letter its value as given above. If
+ the subject sequence begins with a minus sign, the value resulting from the
+ conversion is negated (in the return type). A pointer to the final string
+ is stored in the object pointed to by endptr, provided that endptr is
+ not a null pointer.
+
+ In other than the "C" locale, additional locale-specific subject sequence
+ forms may be accepted.
+
+ If the subject sequence is empty or does not have the expected form, no
+ conversion is performed; the value of nptr is stored in the object pointed
+ to by endptr, provided that endptr is not a null pointer.
+
+ @return The strtol, strtoll, strtoul, and strtoull functions return the
+ converted value, if any. If no conversion could be performed, zero
+ is returned. If the correct value is outside the range of
+ representable values, LONG_MIN, LONG_MAX, LLONG_MIN, LLONG_MAX,
+ ULONG_MAX, or ULLONG_MAX is returned (according to the return type
+ and sign of the value, if any), and the value of the macro ERANGE
+ is stored in errno.
