_putchar

                    void _putchar (char character)

printf() Output a character to a custom device like UART, used by thefunction This function is declared here only. character Character to output You have to write your custom implementation somewhere

printf() _putchar() printf with output function You may use this as dynamic alternative towith its fixedoutput out An output function which takes one character and an argument pointer arg An argument pointer for user data passed to output function format A string that specifies the format of the output The number of characters that are sent to the output function, not counting the terminating null character

printf

printf() printf() putchar if you useTo avoid conflicts with the regularAPI it is overridden by macro defines and internal underscore-appended functions like printf Tiny printf implementation You have to implement() are used. format A string that specifies the format of the output The number of characters that are written into the array, not counting the terminating null character

libs/utils/printf/printf.h:60

snprintf

Tiny snprintf/vsnprintf implementation. buffer A pointer to the buffer where to store the formatted string count The maximum number of characters to store in the buffer, including a terminating null character format A string that specifies the format of the output va A value identifying a variable arguments list The number of characters that COULD have been written into the buffer, not counting the terminating null character. A value equal or larger than count indicates truncation. Only when the returned value is non-negative and less than count, the string has been completely written.

libs/utils/printf/printf.h:85

sprintf

Tiny sprintf implementation Due to security reasons (buffer overflow) YOU SHOULD CONSIDER USING (V)SNPRINTF INSTEAD! buffer A pointer to the buffer where to store the formatted string. MUST be big enough to store the output! format A string that specifies the format of the output The number of characters that are WRITTEN into the buffer, not counting the terminating null character

libs/utils/printf/printf.h:71

vprintf

Tiny vprintf implementation. format A string that specifies the format of the output va A value identifying a variable arguments list The number of characters that are WRITTEN into the buffer, not counting the terminating null character

libs/utils/printf/printf.h:97
