DocGetText

Env::DocGetText

uint32_t DocGetText(const char* szID, char* szRes, uint32_t nLen);

Reads application shader input text argument with name szID. Text could be a unquoted string of characters, in this case ' ' or ',' are not allowed, or text could be a quoted string, in this case any printable characters are allowed, but '"' should be escaped with '\'. For example:

data=some_text_without_spaces0x134

args="Pretty text \"some name\", a = \"test\" n=145 "

Parameters

• szID : 0-terminated string, the name of the argument
• szRes : pointer to the result buffer
• nLen : the size of the result buffer

Return value

• the size of the result in bytes

Notes

• the function copies only min(nLen, <result_size + 1>) bytes
• the result is always 0-terminated

Example

char szAction[0x20];
Env::DocGetText("action", szAction, sizeof(szAction));
