d55e44b2ea Fix sscanf character conversion (%c): do not add '\0' at the end as for strings, cause, for example, parsing one character will fill two bytes: character itself and zero one '\0' after it, so will overflow one byte variable argument and corrupt memory for variables allocated after it. 2017-11-19 13:33:46 -06:00

a325cb9f0d sscanf(): NuttX libc tried to guess how many characters to parse, extracted them into a buffer, then ran strtol() on that buffer. That guess is often wrong. A better approach would be to call strtol() directly on the input data, using the endptr return value to determine how many characters to skip after parsing.

bdf1ad69d6 libc logic should not directly assign errno, but should use set_errno() macro. This is because in the kernel build, errno is a system call 2013-12-11 14:54:22 -06:00

545cef3223 scanf() fixes from kfrolov: 1) sscanf() function hangs in the following example: sscanf(2, %u,%u,%u,%u, ...), 2) sscanf() returns incorrect number of parsed numbers if some arguments can't be parsed: sscanf(=2, %u,%u,%u,%u,...)==1 instead of 0, and 3) using of char* instead of const char* in vsscanf function leads to warnings from GCC. 2013-10-21 10:41:15 -06:00
