kashish_mbed | 0:bacc6e701fb4 | 61 | * @brief Tiny implementation of vsnprintf() like function |
kashish_mbed | 0:bacc6e701fb4 | 62 | * |
kashish_mbed | 0:bacc6e701fb4 | 63 | * It has been adapted so that: |
kashish_mbed | 0:bacc6e701fb4 | 64 | * - Tiny implementation, when defining TINY_PRINTF, is available. In such as case, |
kashish_mbed | 0:bacc6e701fb4 | 65 | * not all the format are available. Instead, only %02X, %x, %d, %u, %s and %c are available. |
kashish_mbed | 0:bacc6e701fb4 | 66 | * %f,, %+, %#, %- and others are excluded |
kashish_mbed | 0:bacc6e701fb4 | 67 | * - Provide a snprintf like implementation. The size of the buffer is provided, |
kashish_mbed | 0:bacc6e701fb4 | 68 | * and the length of the filled buffer is returned (not including the final '\0' char). |
kashish_mbed | 0:bacc6e701fb4 | 69 | * The string may be truncated |
kashish_mbed | 0:bacc6e701fb4 | 70 | * @param Pointer to a buffer where the resulting C-string is stored. The buffer should have a size of |
kashish_mbed | 0:bacc6e701fb4 | 71 | * at least n characters. |
kashish_mbed | 0:bacc6e701fb4 | 72 | * @param Maximum number of bytes to be used in the buffer. The generated string has a length of at |
kashish_mbed | 0:bacc6e701fb4 | 73 | * most n-1, leaving space for the additional terminating null character. |
kashish_mbed | 0:bacc6e701fb4 | 74 | * @param C string that contains a format string that follows the same specifications as format |
kashish_mbed | 0:bacc6e701fb4 | 75 | * in printf (see printf for details). |
kashish_mbed | 0:bacc6e701fb4 | 76 | * @param A value identifying a variable arguments list initialized with va_start. |
kashish_mbed | 0:bacc6e701fb4 | 77 | * @retval The number of written char (note that this is different from vsnprintf() |
