Wording critical to the explanation is in UPPERCASE. - 6.4.4.1 Integer constants - states that '0' is a valid (hexa)decimal - constant, whereas '0x' IS NOT. - 7.19.6.2 The fscanf function - states... - ...in paragraph 9 that "an INPUT ITEM is defined as the longest - sequence of input characters [...] which is, OR IS A PREFIX OF, - a matching input sequence". - ...in paragraph 10 that "if the INPUT ITEM is not a matching - sequence, the execution of THE DIRECTIVE FAILS; this condition - is a matching failure". - ...in footnote 242) that "fscanf pushes back AT MOST ONE input - character onto the input stream." - ...in paragraph 12 that either of the conversion specifiers d, i, - o, u, or x "matches an [...] integer whose format is the same as - expected for THE SUBJECT SEQUENCE of the [strtol|strtoul] - function". - 7.20.1.4 The strtol, strtoll, strtoul, and strtoull functions - states - in paragraph 3 that "the EXPECTED FORM OF THE SUBJECT SEQUENCE is - that of an integer constant AS DESCRIBED IN 6.4.4.1". - These parts of the standard result in the following reasoning: - - The longest sequence of input characters which is a prefix of a - matching input sequence is "-0x" (negative sign, hexadecimal-prefix). - The 'z' is the first character remaining unread as "-0xz" is not a - (prefix of a) matching input sequence. This is according to 7.19.6.2 - paragraph 9. - - "0x", without a valid hexadecimal digit following it, is not a valid - integer constant according to 6.4.4.1. - - "0x" is thus also not of the expected form for a strto[u]l subject - sequence according to 7.20.1.4 paragraph 3. (strto[u]l() would parse - it as zero, but leave the "x" in the final string, i.e. outside the - subject sequence.) - - "0x" is therefore also not a matching sequence to the i or x - conversion specifier according to 7.19.6.2 paragraph 12. - - The conversion should therefore result in a matching failure - according to 7.19.6.2 paragraph 10. - */ - CHECK_EQUAL( sscanf( string, "%hhx%n", &i, &n ), 0 ); - CHECK_EQUAL( i, 1 ); - CHECK_EQUAL( n, -1 ); - } - { - // reading -0x, x - unsigned short i = 1; - int n = -1; - CHECK_EQUAL( sscanf( string, "%hx%n", &i, &n ), 0 ); - CHECK_EQUAL( i, 1 ); - CHECK_EQUAL( n, -1 ); - } - { - // reading -0x, x - unsigned int i = 1; - int n = -1; - CHECK_EQUAL( sscanf( string, "%x%n", &i, &n ), 0 ); - CHECK_EQUAL( i, 1 ); - CHECK_EQUAL( n, -1 ); - } +#define SCANFUNC( source, format, ... ) sscanf( source, format, __VA_ARGS__ ) +#include "sscan_sources.incl" +#include "scanf_testcases.incl" + return TEST_RESULTS; } #endif diff --git a/functions/stdio/vfscanf.c b/functions/stdio/vfscanf.c index a9ce3e9..99a752f 100644 --- a/functions/stdio/vfscanf.c +++ b/functions/stdio/vfscanf.c @@ -83,11 +83,23 @@ int vfscanf( FILE * _PDCLIB_restrict stream, const char * _PDCLIB_restrict forma #ifdef TEST #include <_PDCLIB_test.h> +#include "scan_test.h" + +static int SCANFUNC( FILE * stream, char const * format, ... ) +{ + va_list ap; + va_start( ap, format ); + int result = vfscanf( stream, format, ap ); + va_end( ap ); + return result; +} + int main( void ) { - /* TODO: Check whitespace / EOF / ungetc handling */ - TESTCASE( NO_TESTDRIVER ); +#include "fscan_sources.incl" +#include "scanf_testcases.incl" return TEST_RESULTS; } #endif + diff --git a/functions/stdio/vsscanf.c b/functions/stdio/vsscanf.c index 3fc09cf..8a23790 100644 --- a/functions/stdio/vsscanf.c +++ b/functions/stdio/vsscanf.c @@ -79,20 +79,21 @@ int vsscanf( const char * _PDCLIB_restrict s, const char * _PDCLIB_restrict form #ifdef TEST #include <_PDCLIB_test.h> +#include "scan_test.h" + +static int SCANFUNC( char const * stream, char const * format, ... ) +{ + va_list ap; + va_start( ap, format ); + int result = vsscanf( stream, format, ap ); + va_end( ap ); + return result; +} + int main( void ) { - char const * teststring1 = "abc def"; - char const * teststring2 = "abcdef"; - char const * teststring3 = "abc%def"; - int x; - TESTCASE( sscanf( teststring2, "abcdef%n", &x ) == 0 ); - TESTCASE( x == 6 ); - TESTCASE( sscanf( teststring1, "abc def%n", &x ) == 0 ); - TESTCASE( x == 8 ); - TESTCASE( sscanf( teststring2, "abc def%n", &x ) == 0 ); - TESTCASE( x == 6 ); - TESTCASE( sscanf( teststring3, "abc%%def%n", &x ) == 0 ); - TESTCASE( x == 7 ); +#include "sscan_sources.incl" +#include "scanf_testcases.incl" return TEST_RESULTS; }
