示例1: ReadShaderSource
static bool ReadShaderSource(const char* fileName, ShaderSource& source) {
FILE* in = fopen(fileName, "rb");
if (!in) {
printf("Error: unable to open input file: %s\n", fileName);
return false;
}
// Obtain file size.
fseek(in, 0, SEEK_END);
int count = ftell(in);
rewind(in);
int len = (int)ceil((float)count / (float)NUM_SOURCE_STRINGS);
source.reserve(NUM_SOURCE_STRINGS);
// Notice the usage of do-while instead of a while loop here.
// It is there to handle empty files in which case a single empty
// string is added to vector.
do {
char* data = new char[len + 1];
int nread = fread(data, 1, len, in);
data[nread] = '\0';
source.push_back(data);
count -= nread;
} while (count > 0);
fclose(in);
return true;
}
