Stream manipulator

Description

sycl::flush

Triggers a flush operation, which synchronizes the work-item stream buffer with the global stream buffer, and then empties the work-item stream buffer. After a flush, the full workItemBufferSize is available again for subsequent streaming within the work-item.

sycl::endl

Outputs a new-line character and then triggers a flush operation.

sycl::dec

Outputs any subsequent values in the current statement in decimal base.

sycl::hex

Outputs any subsequent values in the current statement in hexadecimal base.

sycl::oct

Outputs any subsequent values in the current statement in octal base.

sycl::noshowbase

Outputs any subsequent values without the base prefix.

sycl::showbase

Outputs any subsequent values with the base prefix.

sycl::noshowpos

Outputs any subsequent values without a plus sign if the value is positive.

sycl::showpos

Outputs any subsequent values with a plus sign if the value is positive.

sycl::setw(int)

Sets the field width of any subsequent values in the current statement.

sycl::setprecision(int)

Sets the precision of any subsequent values in the current statement.

sycl::fixed

Outputs any subsequent floating-point values in the current statement in fixed notation.

sycl::scientific

Outputs any subsequent floating-point values in the current statement in scientific notation.

sycl::hexfloat

Outputs any subsequent floating-point values in the current statement in hexadecimal notation.

sycl::defaultfloat

Outputs any subsequent floating-point values in the current statement in the default notation.
