[in]list- The variable argument list
Returns
none

◆ __attribute__()

◆ __aeabi_uldivmod()

SceUInt64 __aeabi_uldivmod ( SceUInt64  dividend,
SceUInt64  divisor 
)

ARM EABI unsigned 64-bit division helper.

Parameters
[in]dividend- Dividend.
[in]divisor- Divisor.

On FW 3.60, a zero divisor produces a zero remainder. In that case, the quotient is zero when the dividend is zero, or UINT64_MAX otherwise.

Returns
The quotient. The helper also returns the remainder in R2:R3 as required by the ARM EABI.

◆ __strncat_chk2()

char * __strncat_chk2 ( char *  dest,
const char *  src,
SceSize  dest_size 
)

Append a bounded string and trap if the destination would overflow.

Parameters
[in,out]dest- NUL-terminated destination buffer.
[in]src- Source string.
[in]dest_size- Total destination capacity.
Returns
dest.

◆ __strncpy_chk2()

char * __strncpy_chk2 ( char *  dest,
const char *  src,
SceSize  dest_size 
)

Copy a string after checking its bounded length.

On FW 3.60, this function executes breakpoint 0x81 only if strnlen(src, dest_size) is greater than dest_size. The FW 3.60 strnlen cannot normally produce such a result.

Parameters
[out]dest- Destination buffer.
[in]src- Source string.
[in]dest_size- Number of bytes to copy, padding with NUL bytes when the source is shorter.
Returns
dest.

◆ strncat()

char * strncat ( char *  dest,
const char *  src,
SceSize  count 
)

Append at most count bytes from src to dest and return dest.

When at least one byte is appended, FW 3.60 writes the trailing NUL before copying the source bytes into place.

◆ strncpy_s()

char * strncpy_s ( char *  dest,
const char *  src,
SceSize  dest_size 
)

Copy at most dest_size bytes from a string.

A terminating NUL is written only when the source is shorter than dest_size; unlike the C11 Annex K function with the same name, this FW 3.60 function takes three arguments and returns dest.

Returns
dest.
