|

| 317 | * Usage:
|
|---|
| 318 | * Place CL_PROGRAM_STRING_DEBUG_INFO on the line before the first line of your source.
|
|---|
| 319 | * The first line ends with: CL_PROGRAM_STRING_DEBUG_INFO \"
|
|---|
| 320 | * Each line thereafter of OpenCL C source must end with: \n\
|
|---|
| 321 | * The last line ends in ";
|
|---|
| 322 | *
|
|---|
| 323 | * Example:
|
|---|
| 324 | *
|
|---|
| 325 | * const char *my_program = CL_PROGRAM_STRING_DEBUG_INFO "\
|
|---|
| 326 | * kernel void foo( int a, float * b ) \n\
|
|---|
| 327 | * { \n\
|
|---|
| 328 | * // my comment \n\
|
|---|
| 329 | * *b[ get_global_id(0)] = a; \n\
|
|---|
| 330 | * } \n\
|
|---|
| 331 | * ";
|
|---|
| 332 | *
|
|---|
| 333 | * This should correctly set up the line, (column) and file information for your source
|
|---|
| 334 | * string so you can do source level debugging.
