Macros

#define CBPRINTF_PACKAGE_ALIGNMENT
 Required alignment of the buffer used for packaging.
 
#define CBPRINTF_PACKAGE_CONST_CHAR_RO   BIT(0)
 Assume that const char pointer is pointing to read only (constant) strings.
 
#define CBPRINTF_PACKAGE_ADD_RO_STR_POS   BIT(1)
 Append locations (within the package) of read-only string pointers.
 
#define CBPRINTF_PACKAGE_ADD_RW_STR_POS   BIT(2)
 Append locations (within the package) of read-write string pointers.
 
#define CBPRINTF_PACKAGE_FIRST_RO_STR_CNT(n)    (n << Z_CBPRINTF_PACKAGE_FIRST_RO_STR_OFFSET)
 Indicate that n first string format arguments are char pointers to read-only location.
 
#define CBPRINTF_PACKAGE_ADD_STRING_IDXS    (CBPRINTF_PACKAGE_ADD_RO_STR_POS | CBPRINTF_PACKAGE_CONST_CHAR_RO)
 Append indexes of read-only string arguments in the package.
 
#define CBPRINTF_PACKAGE_ARGS_ARE_TAGGED   BIT(6)
 Indicate the incoming arguments are tagged.
 
#define CBPRINTF_PACKAGE_CONVERT_RO_STR   BIT(0)
 Append read-only strings from source package to destination package.
 
#define CBPRINTF_PACKAGE_COPY_RO_STR   CBPRINTF_PACKAGE_CONVERT_RO_STR __DEPRECATED_MACRO
 
#define CBPRINTF_PACKAGE_CONVERT_RW_STR   BIT(1)
 Append read-write strings from source package to destination package.
 
#define CBPRINTF_PACKAGE_COPY_RW_STR   CBPRINTF_PACKAGE_CONVERT_RW_STR __DEPRECATED_MACRO
 
#define CBPRINTF_PACKAGE_CONVERT_KEEP_RO_STR   BIT(2)
 Keep read-only location indexes in the package.
 
#define CBPRINTF_PACKAGE_COPY_KEEP_RO_STR   CBPRINTF_PACKAGE_CONVERT_KEEP_RO_STR __DEPRECATED_MACRO
 
#define CBPRINTF_PACKAGE_CONVERT_PTR_CHECK   BIT(3)
 Check format string if p argument was treated as s in the package.
 
#define CBPRINTF_MUST_RUNTIME_PACKAGE(flags, ...)    Z_CBPRINTF_MUST_RUNTIME_PACKAGE(flags, __VA_ARGS__)
 Determine if string must be packaged in run time.
 
#define CBPRINTF_STATIC_PACKAGE(packaged, inlen, outlen, align_offset, flags, ...)
 Statically package string.
