#define context_save ( c ) context_save_arch(c)

Save register context.
Save current register context (including stack pointers) to context structure.
Note that call to context_restore() will return at the same address as the corresponding call to context_save().
This MUST be a macro, gcc -O0 does not inline functions even if they are marked inline and context_save_arch must be called from level <= that when context_restore is called.

Parameters:

c Context structure.

Returns:
context_save() returns 1, context_restore() returns 0.

Referenced by scheduler(), thread_create(), and waitq_sleep_timeout_unsafe().

#define context_set ( c,

int printf_core ( const char * fmt,

struct printf_spec * ps,

va_list ap

)

Print formatted string.
Print string formatted according to the fmt parameter and variadic arguments. Each formatting directive must have the following form:
% [ FLAGS ] [ WIDTH ] [ .PRECISION ] [ TYPE ] CONVERSION
FLAGS:

"#" Force to print prefix. For conversion %o the prefix is 0, for x and %X prefixes are 0x and 0X and for conversion %b the prefix is 0b.

"-" Align to left.

"+" Print positive sign just as negative.

" " If the printed number is positive and "+" flag is not set, print space in place of sign.

"0" Print 0 as padding instead of spaces. Zeroes are placed between sign and the rest of the number. This flag is ignored if "-" flag is specified.

WIDTH:

Specify minimal width of printed argument. If it is bigger, width is ignored. If width is specified with a "*" character instead of number, width is taken from parameter list. And integer parameter is expected before parameter for processed conversion specification. If this value is negative its absolute value is taken and the "-" flag is set.

PRECISION:

Value precision. For numbers it specifies minimum valid numbers. Smaller numbers are printed with leading zeroes. Bigger numbers are not affected. Strings with more than precision characters are cut off. Just as with width, an "*" can be used used instead of a number. An integer value is then expected in parameters. When both width and precision are specified using "*", the first parameter is used for width and the second one for precision.

TYPE:

"hh" Signed or unsigned char.

"h" Signed or usigned short.

"" Signed or usigned int (default value).

"l" Signed or usigned long int.

"ll" Signed or usigned long long int.

"z" __native (non-standard extension).

CONVERSION:

% Print percentile character itself.

c Print single character.

s Print zero terminated string. If a NULL value is passed as value, "(NULL)" is printed instead.

P, p Print value of a pointer. Void * value is expected and it is printed in hexadecimal notation with prefix (as with %X or %x for 32bit or %X / %x for 64bit long pointers).

b Print value as unsigned binary number. Prefix is not printed by default. (Nonstandard extension.)

o Print value as unsigned octal number. Prefix is not printed by default.

d,i Print signed decimal number. There is no difference between d and i conversion.

u Print unsigned decimal number.

X, x Print hexadecimal number with upper- or lower-case. Prefix is not printed by default.

All other characters from fmt except the formatting directives are printed in verbatim.

Parameters:

fmt Formatting NULL terminated string.

Returns:
Number of printed characters or negative value on failure.
< i is index of currently processed char from fmt, j is index to the first not printed nonformating character
< counter of printed characters
< used to store return values from called functions
< base in which will be parameter (numbers only) printed
< argument value
< byte size of integer parameter

int vsnprintf_write ( const char * str,

size_t count,

struct vsnprintf_data * data

)

Write string to given buffer. Write at most data->size characters including trailing zero. According to C99, snprintf() has to return number of characters that would have been written if enough space had been available. Hence the return value is not number of really printed characters but size of the input string. Number of really used characters is stored in data->len.
Parameters:

str source string to print

count size of source string

data structure with destination string, counter of used space and total string size.

Returns:
number of characters to print (not characters really printed!)
